On Causality You see, when you ask why something happens, how does a person answer why something happens? For example, Aunt Minnie is in the hospital. Why? Because she went out on the ice and slipped and broke her hip. That satisfies people. But it wouldn't satisfy someone who came from another planet and knew nothing about things... When you explain a why, you have to be in some framework that you've allowed something to be true. Otherwise you're perpetually asking why... You go deeper and deeper in various directions. Why did she slip on the ice? Well, ice is slippery. Everybody knows that-no problem. But you ask why the ice is slippery... And then you're involved with something, because there aren't many things slippery as ice... A solid that's so slippery? Because it is in the case of ice that when you stand on it, they say, momentarily the pressure melts the ice a little bit so that you've got an instantaneous water surface on which you're slipping. Why on ice and not on other things? Because water expands when it freezes. So the pressure tries to undo the expansion and melts it... I'm not answering your question, but I'm telling you how difficult a why question is. You have to know what it is permitted to understand... and what it is you're not. You'll notice in this example that the more I ask why, it gets interesting after a while. That's my idea, that the deeper a thing is, the more interesting... (Richard Feynman) If you know how, then you know why.

I think general relativity is not understandable because it's taught in schools than Newtonian. And even when it's taught, it's taught badly because teachers haven't took time to get a grasp of it. How can you teach something you don't understand! :) GR is easy, one just have to take time and read it through, for starters :)

Comment like motorcycle riding? (Score 4, Informative) 487

Obviously, author has never ridden a motorcycle - he has absolutely no idea, what it takes to ride such thing. On motorcycle, you have a throttle, first brake, rear brake, 6 gears and clutch. To ride it, you have to (ok, don't have to but would be good) understand counter-steering. And on IT? lean yourself and twist the stick. That's all. Pfffff.

Bike Projector Makes Lane For Rider 856

hh4m writes "Whether it's San Francisco, New York, or any bicyclistic city in between, you're destined to witness biker after biker dancing with danger, especially at night when visibility is uncomfortably low. Alex Tee and Evan Gant's LightLane device was recently just a concept but is soon to enter reality as a much-needed visual declaration of personal biking space. With a dire shortage of dedicated lanes, LightLane provides urban cyclists with a solution that adapts to them and any route they make take. The compact projector mounts easily to the rear of a bike frame and projects a bike lane-inspired linear pattern that provides great visibility and a familiarity that helps catch a driver's attention."

Submission + - Google uses Google Docs to mix Linux, Windows

kripkenstein writes: "According to a quoted intern's comment during the recent Ubucon at Google NY, Google uses Google Docs & Spreadsheets internally and thus avoids document interoperability issues between Windows and Linux PCs:

A funny moment near the beginning was when we were asking a Google intern questions. Apparently only the engineers all get Ubuntu on their machines, and other staff have windows because it's "easier." Somebody asked how they deal with interoperability between OO.o and MS Office, and he said "Well, you know we have this product called Google Docs..."
I guess in the case of Google itself, using Google Docs & Spreadsheets means you are still saving your data in-house. Also interesting in the quote is that Google engineers apparently use Ubuntu, while other staff use Windows."
