  1. You explain your kids the clock using the word “modulo”
  2. If you terminate all your sentences with a NULL byte\0
  3. If you extend your 101-keys-keyboard for 42 more keys
  4. If you answer infinity calculations in math courses with “BufferOverflow”
  5. If you have to andl $-16, %esp your priority queue if your boss assigns you a new task
  6. If you think you know more about inheritance than biologists
  7. If execution, command and kill are harmless words for you
  8. If you think that 2 spaces are missing in the source code, but you cannot explain the why to someone else.
  9. If (0.1 + 0.7) * 10 is anything else than 8 for you
  10. You expected a list with 102 elements here

Math behind “Rope around the globe”

Posted by on 2011.09.17 No comments

Some people will know the mathematical problem:

Take a rope and tie it around a tennis ball very tightly. Cut the rope and add an extra meter of length. If you lay the rope around the tennis ball in a circle again, you will get a distance of 16 cm between the rope and the ball.

Now consider the same for the earth. Assuming a perfect globe with an equator of 40 000 km and an additional meter for the rope: What will the distance between earth and the rope be?

Tennis ball (3.35 cm radius):

U1 = 2 × 0.0335 × π
U2 = U1 + 1
r2 = U2 / 2π
r2 = ~0.19265 m
r2 – r1 = 0.19265 – 0.0335 = +0.15915m

Globe (40 000 m radius):

U1 = 2 × 40000 × π
U2 = U1 + 1
r2 = U2 / 2π
r2 = ~40000.1591 m
r2 – r1 = 40000.1591 – 40000 = +0.15915m

Conclusion

The distance is always about 16cm for an additional meter. This comes from the formula r = U / 2π. You can separate the constant from the variables: r2 = U1 / 2π + 1 / 2π. So the 16cm is actually parameter / 2π.

3D Supply: Böses Encoding in Kakhi

Wenn es um Geek-T-Shirts geht, bin ich natürlich wieder dabei :-)

3D Supply hat wieder eine Aktion, wo sie (sofern man Glück hat) T-Shirts verschenken, wenn man einen Link zum Produkt postet. Bestechung im wahrsten Sinne ;-)

Böses Encoding, da es sehr schön eines meiner Lieblingsthemen beschreibt: Internationalisierung, die Verwendung einer einzigen Sprache und der damit verbundenen Technologien :-)
