## I know 50

Daniel would like you to know that he knows 50 digits of pi. He uses groups of 5:

3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510

This is all he knows and he is going to see how far he can get!

## Googling with Googol

Close enough…

Thanks tofor this submission!

I. Input shoe size

II. blah

III. blah

IV. blah

V. blah (Arbitrary number that makes this work, but only for the year 2012)

VI. Input age

Output is your shoe size and age. If you input someone else’s values, it outputs their values back. Magic!

## The Relationship between a Circle and its Radius

The Circle and its Radius are definitely in a relationship, but it’s not complicated. Here is a simple .gif that explains it perfectly.

## 11 Magnificent Wonders of the Ice World

Not a math post, but cool nonetheless:

In polar and other cold regions there are ice, snow and water formations that are unusual, unique, and some of them so beautiful to breathtaking. Most of these wonders of nature can be visited only by scientists and rare adventurers who are ready for significant physical and financial exertions. Because of their volatility and locations, these formations can be seen only at certain periods of the year.

## Maths Dingbats

This is one of my favourite maths dingbats (quite an easy one!) It’s one of over 50 maths dingbats on the website – some easy, some pretty tough.

Thanks to anon for this submission!

Let’s face it. Not all since jokes are easy to understand. Have no fear! Here some of the most common scientific notions which you might come across in a joke.

Physics 1: Newton’s first law states that a body in motion remains in motion and a body at rest remains at rest unless acted upon by an unbalanced force.

General/Miscellaneous 1: Asymmetry sounds like “a cemetery”. Asymmetry in physics and mathematics is a lack of symmetry. Something is symmetric if it is unchanged when transformed. For example, a sphere has rotational symmetry because if you turn it, it looks the same.

Physics 23: The half-life of a radioactive substance is the time it takes for half of it to decay away. Ordinary cats are said to have 9 lives, so the issue is whether a radioactive cat has 9 or 18 half-lives.

Biology 12: The word “staph” is an informal version of staphylococci, a type of spherical parasitic bacteria that bunch together in irregular masses.

Physics 35: According to special relativity, the length of an object decreases as the speed of the object increases.

Chemistry 14: The symbols for carbon, holmium, cobalt, lanthanum and tellurium are respectively C, Ho, Co, La and Te.

Chemistry 22: K is the symbol for potassium.

Chemistry 21: H2SO4 is sulfuric acid. Presumably, Susan drank acid instead of water.

So next time you see a sciency joke, you should understand it, K?
