# Who is the most badass mathematician ever?

**Who is the most badass mathematician ever?**. Do You mate own that kind of problem?, If yes then plz read the answer right after below:

The following problem can be solved the easy way or the hard way:

“Two trains 200 miles apart are moving toward each other; each one is going at a speed of 50 miles per hour. A fly starting on the front of one of the trains flies back and forth between them at a rate of 75 miles per hour. It does this until the trains collide and crush the fly to death. What is the total distance the fly has flown?”

In a strict mathematical sense the fly actually hits each train an infinite number of times before it gets crushed, and one could solve the problem the hard way with pencil and paper by summing an infinite series of distances. This is they way that most trained mathematicians will solve the problem. Conversely a mathematical novice will most likely solve the problem the easy way – since the trains are 200 miles apart and each train is going 50 miles an hour, it takes 2 hours for the trains to collide, therefore the fly was flying for two hours, at a rate of 75 miles per hour, and so the fly must have flown 150 miles. Easy.

When this problem was posed to John von Neumann, he immediately replied*, “***150 miles***.”“Ah, I see you’ve heard this one before, Professor von Neumann. Nearly everyone tries to sum the infinite series.”“What do you mean?” *asked von Neumann

*“That’s how I did it!*(He summed an infinite series in a moment!)

Badass level [math]tan(fracÏ2)[/math] !

Yes, this is the great polymath, John Von Neumann.

Here’s what his teacher said about him:

And the geniuses view on math:

But surely math was *easy *for him.

Not only math, but he contributed to all the fields of natural sciences, from computers to nuclear physics.

And of course, you can read more about him here: John von Neumann

We at this web hope that those answers above can solve your problem. Take care
