Re: 0895: "Teaching Physics"

I had this same objection because the rubber sheet explanation is usually used to explain gravity, but the example itself depends on understanding gravity. Actually, it doesn't. You don't need to understand gravity to know that a ball placed on a rubber sheet will pull the sheet down. That you can ...

Possible solution

This is probably stupid, but once you look at the problem in binary it becomes clearer. In binary all odd numbers end with a 1 and whenever you have a number with zeroes at the end, you just bitshift it down until you get a one instead. Then it becomes clear that the 3x+1-operation equals x + 2x + 1...

Re: "Revolutionary" Discussion

Wrong. Blah blah, stupid reasoning, blah Actually, strike that, I forgot that since space contracts when time dilates, the distance travelled on the train cancels the time dilation out. So going 0.5c in one direction and 0.5c in the other actually DOES cancel eachother out so that the speed relativ...

Re: "Revolutionary" Discussion

Special relativity implies time dilation: moving clocks go slower than stationary clocks. So let's say that you're standing still, and a racecar goes by you at half the speed of light - the racecar's clock goes slower than your clock. But actually, you and the racecar are on a train moving at half ...

Re: "Free" Discussion

In Australia at least there are annoying claims like "97%" fat-free, as though all the fat is in just 3% of the product. Usually the fat is distributed throughout the whole damn thing - *none* of it is "fat free". Also, some chips claim "50% less fat than those cooked in pa...

Re: Guest Comics! xkcd outside of xkcd.com

You are confusing simplistic drawing with bad drawing. If you've watched Randall's Google lecture, you'd know that he's very good at drawing and he shows it off in the strip every now and then. Oftentimes it is much harder to make people understand exactly what a character is doing with just a stick...
