What Are Some Ways to Keep My Hair Really Healthy?
What Are Some Ways to Keep My Hair Really Healthy?
Use professional shampoo & conditioner. I know it may seem like a rip-off, however all the shampoos like Pantene, Garnier, etc. have a high alcohol content....since the normal pH of your hair is 4.5-5.5, things containing high amounts of alcohol throw your hair all out of whack and cause breakage, split-ends, fly-aways, etc. The reason these shampoos make your hair feel soft is because they contain high amounts of humectants, which are just a cover for how damaging they really are! Another tip is ALWAYS use a thermal protector while applying heat. Heat appliances cause tons of damage to your hair. Usually this is a cream/clear gel you apply before blow drying. Never use a flat iron on hair that is not completely dry!1. Split End Help. ( 10 Points) !!!!!!!!!!!!!!!!!!!!!!?For sure you should get a trim and maybe even cut your hair as short as you are comfortable doing it. You should for no reason straighten or dye your hair. Look for some Garnier Fructis or Pantene shampoos and conditioner for curly hair so that it extra moisturizes it and helps the split ends repair themselves. I say from experience that ppl with curly hair have really bad split ends, which is why we have special stuff in our hair products. The split ends wont magically go away in like a month or a few weeks, but you will see improvement after a while. Oh, and for sure DO NOT PICK THEM OFF!! It will just make it worse. Every two months until your hair is healthy get a trim. just maybe half an inch or an inch will be just fine. Eventually your hair will go back to normal. Good luck with that!.2. Whats the best shampoo conditioner for cheap?clever or V05 are solid inexpensive ($a million) shampoos, yet whilst it is composed of conditioner i could bypass Tresemme ($6) it does an somewhat solid interest. i take advantage of salon shampoo because of the fact i am form of a hair snob, yet I nonetheless use the cheap conditioner. Pantene is undesirable on your hair (too plenty protein and reasons alot of greater build up on the hair) so i does not bypass there. desire this permits! My hair is oily, superb, and colour-taken care of if that helps you any!3. How can I get my curly hair to be nice like Taylor Swift?Haha i have the same hair long and curly..but not pretty curly! im completely obsessed with taylor and her hair so i did so playing with it and what you really NEED to get is the conair hot sticks!! they are these little flexible curlers and they are not very expensive and i would look like a frizz ball without them!! you can like get them at walmart. anyways what i do when iwear my hair curly is like i get up and get in the shower and wash it and condition it and this may sound weird but dont use a whole lot of conditioner just enough to get it done cause it will help your hair hold the curl the just get out and towel dry your hair till it is just damp and then put a curling mouse in it and frizz serum then finish blow drying it straight! and you know have the curlers on like when your gettin in the shower and then just make sure the little light is on meaning that they are hot enough and then seperate your hair into pretty small peices (if you have really thick hair then you might need to buy two sets cause they only have 14 in them and you use small sections) and then start from the botom of your hair and role it through your hair and pin it together youll see the instructions on how to pin them together and make sure you wrap it all the way to the top of your head and leave them for like 15 or 20 minutes while your finishin gettin ready and then use like a light hairspray about 5 minutes before you take them out then your done. i know this thing was really long but its not that hard lol!!!! hope i helped good luck!!!!!!!!

Wayve's Commitment to Developing the Temporal Prediction Model Is the Key to Building an Intelligent
Wayve, a team founded by the Engineering Department of University of Cambridge, relies on machine learning algorithms, which only require the use of cameras and basic satellite navigation to achieve automatic driving on unfamiliar roads.Since deep learning technology was introduced in 2016, after numerous technologies, demo has been used too many to count on the technology of automatic driving. The simple network structure can realize the direct mapping from the camera input to the brake throttle steering wheel output. However, this low threshold also doomed that it can solve few problems, and it is difficult to deal with the complexity of the specific driving environment. Some experts even think that end-to-end is not suitable for the development of practical driverless system. It can be demo, and large-scale commercial use may be very difficult.End to end only for demo? Wayve driverless software, founded by the Cambridge University team, doesn't think so. They did not use high-precision maps, nor did they use expensive sensors such as lidar. Of course, they did not manually enter rules for cars. They only trained 20 hours of data and could drive on roads they had never run.The wave R & D team believes that since it is automatic driving, it does not need to manually code some regulations and fully show its intelligent characteristics. The team adopted the current deep learning and reinforcement learning algorithm, and built an automatic driving system that can learn to drive slowly as human beings do.After three steps of exploration, optimization and evaluation, deep deterministic policy gradients (ddpg) is adopted to solve the lane keeping problem.The image classification architecture of the prior art has millions of parameters, while the network architecture of the wave team is a deep network with four convolution layers and three fully connected layers, with a total of less than 10000 parameters. All processing is performed on the automotive GPU.In the reinforcement learning simulation test, the curve lane, road texture and lane mark are randomly generated, and then the strategy is optimized according to the collected data, and then repeated.An end-to-end zero shot framework combining image translation and behavior cloningMost self driving companies use simulations to verify their systems, while Wayve allows autopilot to learn extensively in simulation how to handle rare edge situations. Wave trains cars to simulate driving and transforms the knowledge learned into the real world.Instead of treating simulation and the real world as two different fields, wave has designed a framework to combine the two, which can not only train to decision-making in simulation, but also show similar behavior in the real world without real demonstration.Wave's model consists of a pair of convolutional variational automatic encoder networks originally used for image conversion for image translation, that is, unsupervised image to image translation networks (unit)). The model can transform between two domains without any known alignment or correspondence. The following figure is an example of capturing the main layout of the scene. It is worth noting that the visual fidelity of the simulator is not the most important when learning to drive. Their simulation world is like a cartoon, which can still complete the simulation well. According to wave research, content fidelity is more important than visual fidelity. However, effectively simulating the behavior of other traffic participants is still a great challenge.Simulate the scene based on real-world driving data and well-designed edge casesThe vehicle is driven by a model-based deep reinforcement learning system, which learns the prediction model from the real data collected offline. This allows the model to learn and use the new scene data imagined by the prediction model to train driving.Wayve is committed to developing a richer and more powerful temporal prediction model, and believes that this is the key to building intelligent and safe autopilot.At present, the system has been deployed on jaguari-pace. The car won the title of European model of the year in 2019 and will collect data throughout the UK and the European continent in the future. At present, let the data accumulate gradually, and its driving algorithm may reach 95% of the quality of human drivers, and can handle traffic lights, roundabouts, intersections, etc.Although some people would think that the automatic driving system with end to end is neither smart nor flexible, it is difficult to explain the problems. However, Wayve is using its powerful algorithm to prove that this deep learning technology can not only be demo, but also guarantee safety and business in the future.Wayve is committed to developing a richer and more powerful temporal prediction model, and believes that this is the key to building intelligent and safe autopilot.

Many IT products are moving towards wireless in recent years, especially after smart phones have become a necessary tool for people, various products controlled by mobile app came into being. I believe that most of my friends' mobile phones are equipped with video software. If we can easily put TV dramas and film resources on the TV or monitor, it will be very popular. In the past, users who used the TV box may not adapt to the corresponding system and remote control. In addition, the practicability of the TV box is greatly reduced after it is limited by various restrictions.Iqiyi TV fruit 3 recommended for you today breaks all kinds of cumbersome operations and resource limitations, and brings a relaxed and convenient smooth large screen viewing experience. As the third generation of TV fruit series products, TV fruit 3 is positioned as the connection bridge between mobile devices and TV. Its core function realizes one click projection, and the content on the mobile phone can be freely displayed on the large TV screen for barrier free viewing. It solves the problem that the video screen on the mobile phone is too small and the content of the TV and Internet connection port is far from enough. It has unprecedented practicability, Take you into a new era of projection.2 overview of packaging and appearanceOverview of packaging and appearanceIqiyi TV fruit 3 has simple and beautiful packaging, and the product effect picture of TV fruit is on the front.There is an application icon on the other side, and it is marked with "tap the screen, and the mobile video app, photos, music and games can be moved to the TV in one second". I believe that even friends who did not know the TV results in the past can understand the main function of this product in seconds.It can be seen from the side of the package that the specific model of this TV fruit is M1. As it is the third generation product of TV fruit, it is called TV fruit 3 for short. At the same time, it is also marked that this product is a black monthly card version, indicating that iqiyi VIP members for 1 month are attached.Take out all items in the package. In addition to the TV results and instructions, it is equipped with a micro USB data power supply cable and a mini HDMI to HDMI video transmission cable.Iqiyi TV fruit 3 wiring diagramIqiyi TV fruit 3, as the third generation product, adopts a cake shape, which is more beautiful and smaller. Frosted feel on the front and back, non reflective. On the front is the iqiyi logo.There is 3C certification mark and product name and model on the back, including a small white dot, which is the power indicator, which will light up when powered on.The side of TV fruit 3 is surrounded by a bright surface, which is different from the front, so that the whole product is not monotonous and rigid. No matter where it is placed, it will bring the appearance of decorative effect.The measured diameter of the product is 53.25mm, and the thickest part in the middle is only about 14mm, which is a little thicker than the smartphone. Of course, the interface and reset keys are set on the side.One side of TV fruit 3 is equipped with micro USB power supply interface and reset button. Among them, the power input is DC 5v-1a. The USB interface of TV can meet the power supply demand, and there is no need to connect another charger.The other side is the output Mini HDMI interface. In addition to the reasonable design, TV fruit 3 is also praised for its strong universality and wide range of use of HDMI interface. As long as any device has HDMI interface, it can be connected with TV, including but not limited to projector, display, etc.3 trial experienceTrial experienceAfter knowing the appearance, interface and application scope of iqiyi TV fruit 3, you will enter the trial experience. This time, large screen TV and Android mobile phone are used to introduce the use and effect of TV fruit 3. First understand the hardware parameters of TV fruit 3, support two projection modes of airplay and DLNA, and adopt quad core arm cortex A7 CPU processor and quad core mali-450 GPU display core. It supports 2.4G and 5g WiFi connections, and video output supports HDMI 1.4b interface. Meanwhile, the March card version of TV fruit comes with a one month iqiyi VIP member. After the first connection, you can scan the code according to the prompt and log in to iqiyi's account.After connecting iqiyi TV fruit 3 to the TV, turn on the TV and switch to the corresponding HDMI interface to see the initial code scanning download app interface. It should be noted that the only key on the side of TV fruit 3 is the reset key, not a switch. Just connect the USB power supply line, and TV fruit 3 will turn on automatically. The first step of the initial interface is to scan the code and download the TV fruit app. The second step is to open the mobile app to connect WiFi for the TV fruit, and easily complete the device connection in two steps.After successfully connecting WiFi to the TV, the main interface is similar to the style of a box, but it is extremely simple. However, it is not important, but the current popular dramas and movies are recommended.Super multi TV channels optionalExperience the TV channel broadcasting function immediately. There are many TV channels in the TV fruit app. Select the popular HD CCTV5 sports channel here, and you can see that the picture quality is very smooth and clear. Trying to switch all kinds of popular channels is quite fast.However, the picture quality of some non HD channels is not ideal. Here, try standard definition Shenzhen satellite TV. The picture is fuzzy and the overall picture is smooth, which is suitable for users with slow network speed at home.In addition to the smooth broadcasting and switching of various popular program channels, there are some exclusive special program channels, similar to the paid program channels in digital TV. Although they can be opened, they have limited resources and slow loading speed, which is difficult to play.Common TV functions are concerned by users, and network video has attracted much attention. Iqiyi TV fruit 3 supports iqiyi, Tencent, Youku, Tudou and other video websites, covering almost the whole network. At the same time, TV fruit supports video projection such as Baidu online disk, which is not limited by the content of app, which integrates almost all the resources of video websites on the Internet.Various TV channels and network resources show the super practicability of iqiyi TV fruit 3. Let's look at the main screen projection function of this product. Here, the author divides the screen projection function into two types: direct screen projection and indirect screen projection.Click screen projection in the main interface of mobile app to directly project the mobile screen on the TV, which is also the simplest direct screen projection method. At this time, the TV picture changes with the mobile phone in real time. Users can directly put documents, PPT, web pages, etc. in equal proportion on the TV screen, which is suitable for office use. Of course, after the mobile phone turns on the game function, you can also move the game picture to the TV screen to share the game experience, but it is not suitable for watching the TV picture to play games, because the game picture transmitted wirelessly is a little delayed, and the frame will drop occasionally.Indirect screen projection generally needs to be completed through other apps. The advantage is that the screen projection can be completed in the background, that is, during the screen projection, users can still use mobile phones to chat and browse web pages without interfering with users' normal use of mobile phones.The operation method is also very simple. Before preparing to cast the screen, the TV app will give tutorial teaching. Use your mobile phone to select a TV play or movie, and you will jump to the app of the video resource. For example, this time the author chose to play the TV play "spring breeze is not as good as you". The video is Youku resource. Then he will jump to Youku app on his mobile phone, and then click the "TV" screen above to start playing the picture. The mobile phone picture will switch to the remote control state. You can drag the progress bar and adjust the volume. Of course, you can also click the home key to make it run in the background, The user can continue to use the mobile phone to complete other tasks.It is similar to projecting music on TV. It is played by TV sound.You can also directly screen the video resources stored in the mobile phone. For example, this time, the author uses the movie video memory master in the mobile phone to directly screen on the TV, and the mobile phone will automatically switch to the remote control interface. Because it belongs to local resources, it is very smooth to drag the progress bar at will. More functions and settings are simple and clear, so I won't introduce them one by one.4 evaluation and summaryEvaluation and summaryThink back to the earliest TV sets. You can watch TV by connecting to the antenna; Later, there were cable TV, digital TV and IPTV, which needed external TV set-top boxes and other equipment. It was difficult to replace them to other equipment at will, such as switching to monitors or projectors, which was inconvenient to move. Although the popular TV box in recent years is easy to connect with different display devices, it needs to be equipped with a switching remote control. The system operation may be cumbersome and subject to many restrictions. Ordinary users do not consider using it.When iqiyi TV completes the powerful screen projection function with smart phones in an extremely simple way, it is instantly loved by public users. In particular, the simple connection seems to return to the beautiful era when you could watch TV by inserting an antenna. In addition to being applied to LCD TV and projector, many users will choose to install it on the LCD with HDMI interface and built-in speaker, so that the computer display in the bedroom or study can also be turned into a TV in one second.Not only limited to video entertainment, the function of screen projection is often used in work, such as document and PPT display. With the lightweight and portable iqiyi TV fruit 3, you can be competent for screen projection no matter where you go.In the actual use experience of iqiyi TV fruit 3, it is found that this projection device has many advantages. Only the performance of switching channels with little delay can make the vast majority of users very satisfied. It can be said that it is very good in the experience of using TV functions. In addition, the screen projection function is also rich and perfect. In most cases, it does not occupy the performance resources of the mobile phone. Even when the mobile phone video and music are played and the background operation is switched, the user can still continue to use the mobile phone to complete other work. Only in the use of game projection, users can feel a certain delay, so the game projection is only suitable for sharing and viewing, and is not suitable for directly watching the screen after projection. This is also a problem that has not been completely solved by various wireless projection so far. Overall, iqiyi TV fruit 3 product itself has a very good positioning. Various performances in the evaluation can satisfy users and are worthy of recommendation.
Google Voice Input Method Can Be Recognized Offline!
This time, it is the Google AI team. Just now, they launched a new function for their mobile phone input method gbboard (don't get confused with Google Pinyin input method ): offline speech recognition. At present, this new function can only be used on its own product pixel series mobile phones.The majority of people outside the pixel circle who have downloaded or are on the way to download, including IOS users, may be disappointed.This is how they describe the configuration of this new function: an end-to-end, all neural, locally deployed speech recognition system.In their recent paper "streaming end to end speech recognition for mobile devices", they proposed a training model based on rnn-t (RNN translator).It is very compact and can be deployed on mobile phones. This means that there will not be too many network delays or disturbances, and the speech recognition system will always be available even if the user is offline. The model always works at the character level, so even if you speak, it will output words character by character, just as someone is typing in real time and listening and writing exactly on the virtual keyboard.For example, the following two pictures show the situation when inputting the same sentence in the dictation system: the server side on the left and the local side on the right. Which side of the speech recognition experience is better?To sum up, "there is no delay when offline." this is also the big killer displayed by Google this time.The delay occurs because your voice data must be transmitted from the mobile phone to the server and returned after parsing. This may take milliseconds or even seconds. If the voice packet is lost in Ethernet, it will take longer.Converting speech into millisecond text requires considerable computational power. This is not just as simple as hearing a voice and then writing a word, but needs to understand the meaning of a person's speech and many contexts related to language and intention.This can be done on mobile phones, but in this case, it will consume the battery power.A brief history of speech recognition modelsGenerally speaking, a speech recognition system consists of several parts: an acoustic model that maps audio clips (usually 10 millisecond frames) to phonemes, a vocal model that connects phonemes to form words, and a language model that expresses a given model. In early systems, these components were optimized relatively independently.Around 2014, researchers began to focus on training a single neural network to map the input audio waveform directly to the output sentence. The model is learned by generating a series of words or glyphs given a series of audio features. This sequence to sequence method promotes the birth of attention based and listen append spell (LAS) models. Although these models show great prospects in accuracy, they usually check the whole input sequence and do not allow output at the time of input, which is a necessary feature of real-time speech transcription.At the same time, a technology called connectionist temporary classification (CTC) helps to reduce the delay of the identification system at that time. This is an important milestone for the later creation of rnn-t architecture and is also regarded as a generalization of CTC technology.(editor's note: CTC, whose full name is connectionist temporary classification, was proposed by Graves et al. In 2006 to train recurrent neural networks (RNNs) To solve the problem of sequence with variable timing. It can be used for online handwriting recognition or recognition of phonemes in speech and audio. Up to now, CTC is no longer a new term, and its application in industry is very mature. For example, in the online speech recognition input method recently released by Baidu, its latest speech model also integrates new technologies such as attention on the basis of CTC.)What is rnn-t?Rnn-t is a sequence to sequence model without attention mechanism. Unlike most sequence to sequence models, which usually need to process the entire input sequence (waveform in speech recognition) to generate output sentences, rnn-t continuously processes input samples and stream output symbols.The output symbol is a character of the alphabet. Rnn-t will output characters one by one and enter spaces in appropriate positions. It does this through a feedback loop, which feeds back the symbols predicted by the model to predict the next symbol. As shown in the figure below.Rnn-t is represented by input audio sample X and prediction symbol y. The prediction symbols (the output of the softmax layer) are fed back into the model through the prediction network.It is difficult to train such a model effectively, but with the newly developed training technology, the word error rate is further reduced by 5%, and its computational intensity becomes higher. In order to solve this problem, researchers have developed a parallel implementation process, so the rnn-t loss function can be run in large quantities on Google cloud TPU v2. About 3x acceleration was achieved in training.off-line recognition In traditional speech recognition engines, acoustic, vocal and speech models are combined into a large search graph, and its edges are marked by speech units and their probabilities. When the speech waveform is presented to the recognition system, the "decoder" will search the path with the highest similarity in the figure and read out the word sequence adopted by the path when the input signal is given. Generally, the decoder is represented by the finite state transducer (FST) of the basic model. However, despite complex decoding techniques, graph search is still difficult because the production model is almost 2GB in size. This can not be realized by hosting on the mobile phone, so this method needs an online connection to work normally.In order to improve the effectiveness of speech recognition, researchers try to host the new model directly on the device to avoid the delay and inherent unreliability of the communication network. Therefore, the end-to-end method does not need to search on a large decoder graph. Instead, the decoder includes a beam search through a single neural network. Rnn-t has the same accuracy as the traditional server-based model, but the former only has 450MB, and uses parameters and packaging information more intelligently. But even on today's smart phones, 450MB still takes up a lot of space. For example, the signal propagation through large networks may be very slow.Therefore, researchers further reduced the model size by using parameter quantization and hybrid kernel technology. This technology was released as early as 2016 and provides a public model optimization toolkit in tensorflow Lite. Compared with the trained floating-point model, model quantization provides 4x compression and 4x acceleration at runtime, which makes rnn-t run faster than real-time speech on a single core. After compression, the final model size is only 80mb.What's the effect?After Google announced this new feature, techcrunch commented, "given that almost none of Google's other products work offline, will you write an email offline? Of course, in the case of poor network conditions, this new feature of the application may solve users' pain points, but obviously, it's still a little ironic (chicken ribs)."This once attracted many users' comments on Hacker News, and they also pointed some of the spearheads at the so-called "offline function":"Although the offline function is not the main attraction, as mentioned in this article, the reduction of latency is huge. What they may not mention is the impact on privacy. However, users generally do not deal with things offline, but if they need a stable packet flow back and forth, connecting to the network is also a troublesome problem."However, after trying, users are still very optimistic: "I just switched my pixel 1 generation to the flight model and tried voice input. Sure enough, it works very fast offline! This is very impressive (I have tried before, but it can only understand some special phrases in the past.)How good are there ways to do this, but I think any application can benefit from this voice improvement“To this end, the battalion commander also specially downloaded the voice input methods of gbboard, iFLYTEK and Baidu to see how they work in flight mode.Round 1Gboard: at present, offline voice in non pixel mobile phones cannot be used, and voice is not even supported for some models. However, typing is still smooth and smooth.Round 2IFLYTEK: offline voice packets can be downloaded, but under the normal condition of smooth network, the speed and accuracy of voice recognition are still quite high.Round 3Baidu: you can also download offline voice. When there is no network connection, the voice recognition effect is still OK.I don't know the partners who often use iFLYTEK and Baidu input method in China. What do you think of this news?

Connect to Nonencrypted Wireless Network Using Ubuntu Commands
Connect to Nonencrypted Wireless Network Using Ubuntu Commands
Connect to Nonencrypted Wireless Network Using Ubuntu Commandsthe output from /sbin/iwconfig wlan0 shows you are not associated with any APs.you will need to do /sbin/iwlist wlan0 scan to search for nearby APs, before, and in my experience, sometimes after, you set /sbin/iwconfig wlan0 essid "essid"again, the app wicd is quite nice for managing your wireless, without requiring a lot of extras— — — — — —how to hack into a wireless network?While cracking a wireless security key is somewhat of a grey area legally, using someone elses internet without permission is a crime. But, a google search for WEP cracking might point you in right direction, but no recommended to do so.— — — — — —How to network a house, both wireless and wired.?The best way would be to recreate the wired network, then set up a wireless network. Use a computer to bridge them together— — — — — —Is it possible to extend the range of your wireless network?You have a couple of different options at your disposal. One is getting higher dbi gain antennas for your ROUTER. The second is adding a higher gain dbi antenna to your adapter (optionally, you can do both and really extend the range). Another is getting a range extender. The higher dbi gain antenna plugged into your router and adapter can really extend your network. Without any obstructions, and 15 dbi gain antennas, you can connect at about 2 miles away. The range extender might be a little cheaper. It plugs into an electrical socket and you run an ethernet cable right into it. This is good if you have quite a few walls in between you and router. Not practical if you do not like wires, you would be better off with the antennas. Regards, Brandon— — — — — —Is it a good idea to download something from an unsecured network?If you see that a wireless network says it's "unsecured", this only means that that wireless network does not have a wireless password. Hence, you or anyone can readily connect to it without entering a password. There is minimal risk of you getting a virus just because of connecting to an "unsecured network", except probably if you go to a website or accidentally downloaded an email that has a virus attached to it - things of that sort. Another risk, although very negligible, is that other people who are connected to that same unsecured network may access your computer files given that you have set your computer files to be on SHARED mode. This is HARDLY ever the case, since you will need to grant that person permission via the Windows File Sharing application. So I tell you, it's okay.— — — — — —XBOX 360 WIRELESS NETWORK ADAPTER BYPASS?There are a number of possible solutions here, but they all depend on you having existing hardware that would cost significantly more than the adapter. Firstly, if you have/buy one of the new "slim" xbox 360s, they have wireless built in, so no need for an adapter. Second, if you have a computer connected to the internet near the 360, you can use the laptop as a wireless receiver, then run an ethernet (CAT5) cable from the laptop to your 360. Thirdly, if you have a computer nearby that is connected by a wired connection (cables through the roof etc) then you can use that computer as a router, and plug the xbox into the computer to share connection. If you just have an xbox 360 original in a room that has no wired connection or a computer connected to wireless, your only option is to buy the adapter.— — — — — —Problems with Wireless Network internet connectionWich encryption type do you use? Maybe the router is set to WPA or WPA2 but your PC does only support WEP— — — — — —Setting up a wireless network..?1) Make sure you are on the same Workgroup, ie, both laptop and desktop have same name. 2) Make sure to turn off all software firewalls for setup puroses. 3) Install/enable file/print sharing in Network Connections. 4) Share a folder on each computer, I usually use c:temp, and then map them to each other computer. 5) sometimes you may have to install Netbios/IPX protocol. email/IM me for more help, Good luck!— — — — — —Wireless network card installation problems.?Switch to a USB wireless.

Is Time Travel Possible? Can We Travel Back in Time?
Is Time Travel Possible? Can We Travel Back in Time?
There is no actual "correct." Einstein made a "theory," not a fact. If Einstein's theory is correct, we could theoretically travel back in time but the problem is, we would not be able to go into the future1. What's the similarities between time travel and space travel?The faster your motion through space relative to a stationary reference frame, the more your motion is diverted from your motion through time. In other words, in a very specific sense, we move through time at lightspeed. The faster you move through space, the more your movement through time is diverted by your movement through space. At lightspeed, all your motion through time is diverted by your motion through space. A photon does not experience time. All of its motion through time is diverted by its motion through space. According to relativity theory anyway2. How to travel with cats?Some cats do fine being loose in the car. Try taking them for a little ride (5-10 minutes) and see how they react. I had one cat, a wonderful loving tabby, that I took for a car ride. I was not driving, so she crawled into my lap, squalled, and peed all over my lap! Some years later I had 3 Siamese, and drove from Wisconsin to Montana with them loose in the car, without a bit of a problem. I think its great that you are taking your cats along with you!!!3. Is it Cheap to Travel to Trinidad?It all depends on where you are flying from. If you are in the US it might be better for you to go to Miami. For me in the Caribbean, I would definitely go to Trinidad because the fair is cheaper, the prices are not that bad, I know my way around and I would feel safe. I can just go down town and buy a few doubles and just watch the people go buy sitting on the side of the road. You might not want to do that. I might even buy some shark and bake. Generally, I go to Chaguanas and shop but I might just stay in POS. From the time I take to spend that extra money to go to Miami I could stop right here in Trinidad. I have been there many times and I have not have a problem. It is up to you though because my experiences might be different to yours. All you have to do is to stay where there is lots of people and the same precautions you would take in your country take there. Do not walk around with your purse expose because that would be asking for trouble.4. Is it safe to travel to Israel?Of course it's safe. It's safer than the US. all that stuff you hear is media bullS5. Where to travel in Europe?You can visit Norway :)6. How do I learn about mountain bikes?Firstly, size. Also, go and have a look at a few of their bikes, there is an interesting rating system next to the bikes, indicating the type of riding that it is suitable for. Next, using 1 - 10 scale. But this is based upon components, layout and value for money. MBR is a good place to do some research. For general bike buying, it is advisable to stick to some of the bigger brands. Trek, Scott, Giant, Specialized. You might also consider some of the smaller manufacturers like Claude Butler or Dawes. For components use either SRAM or Shimano gears. Cranks, either Shimano or Truvative, although if you want to throw money at this you could easily look at 2 - 300 on Race Face or Hollowtec. However, many manufacturers use their own brand, eg. Bontager = Trek. However, if you stick with the brands listed above, they will use viable kit, it just depends how much money that you want to spend on your bike. Hard tail or full sus? Firstly, do not spend less than 700 on a full sus. Do not buy an all singing, all dancing 200 bike from Walmart, Tesco, Cycleking, etc. Hard tails tend to be lighter. Also, because you are not spending huge amounts on a rear shock, you get better quality components elsewhere. So, spending 700 on a hardtail will get you a nice race machine with good quality components and viable suspension. You will still get a nice full sus for this price, but the overall quality will not be as high. If you are just hitting well maintained gravel tracks and roads, you do not want your front fork to do too much, so 80mm travel is good. This is also good if you want to race, since you lose less forward power to bouncy forks. For general XC, about 100mm fork travel, although an adjustable fork between 80 and 130 mm is OK. Any fork that starts at 120mm travel will tend to fall into the all mountain category. These will have chunkyer tyres than XC and are better for bounlders and logs etc. Downhill will have a lot of travel up front, with a raked back design. Luck
