Gravitas

So what's up with gravity? Why is it so physically baffling? It seems to me it is just a question of objects' density versus that of the air. Like when I jump, I land back down because I'm more dense than air. However, a balloon filled with helium is less dense thus floats. There you go gravity explained. But then again, my explanation conveniently forgets the orbit part.

Also, Archimedes proved that a sphere has two thirds of the volume and surface area of a surrounding cylinder (including the bases of the latter), and regarded this as the greatest of his mathematical achievements.

I could watch this all day

Hope you're ready for this:



It seems better than a wood-chipper for, hum, disposing of things.

And I hope it plays that music when you turn it on.

Math Time

Say you want to know whether 586021491 is evenly divisible by 11.

Add up every other digit: 5 + 6 + 2 + 4 + 1 = 18 Add up the other digits: 8 + 0 + 1 + 9 = 18

If those numbers are the same, or the difference between them is a multiple of 11, then the original number is a multiple of 11 too!

Intuitive explanation: see, every time you add 11 or 110 or 1100 etc. to a number without any "carrying" it always contributes 1 to each of those two groups defined above, so the difference between them stays the same. Whereas a "carry" operation removes ten from one group and adds one to the other, which still keeps the difference between the groups a multiple of 11.

Watch this twice

Priceless



Well actually, it's $7

You know you're in 2011 when...

Well ladies and gentlemen, a new age is upon us. It's funny how new technologies inevitably create new subcultures. Cars led to racing and douchebags, motorcycles led to gangs, computers led to online gamers, etc, etc, etc.... There are always small pockets of people that revel in these inventions. Well.... I saw something new the other night... something... I guess new is the best way to explain it.

You might have noticed that there are a lot more electric scooters on the roads these days. You may also have noticed that some of these people believe they have the right to use bike paths (I don't know where they got that idea). Apparently, these electric scooter fatties have taken it upon themselves to create a new subculture! Yes, that's right, if you own an electric scooter, have fat friends with scooters, and know how to rig up LEDs, then your on your way!! I present to you the "LED Bikepath Electric Fatty Gang"



My only wish is that I had a better photo. These guys were glowing!! Keep your eyes open for these silent marauders. They're gone in a flash!

Oh.. and when I asked the beautiful lady on the left what her name was, she just looked at me and said this.
