The Paradox of Time Travel May Have Been Solved by an Undergrad

He wants to be a physicist, so he does a bunch of math and gets a job in a lab. But he's not happy and quits. He then does a bunch of math and gets a job as a Professor of Philosophy. But he's not happy and quits again. He then does a bunch of math and gets a job as a visiting professor at a major research university. He's not happy and quits again. Finally, he gets a job at a small college. He's happy and he's doing math on the side.

That's my story, and it's not the one that the author, Professor James P. Hogan, would tell it. In fact, it's not even the story that Hogan would tell it if he were to write it himself. What Hogan would tell it is that he quit his job at that last college and moved to a remote island, where he has lived ever since.

The fact is, Hogan has spent the last 14 years of his life doing math.

A graduate student at MIT, Hogan got a job in a lab at Harvard in the 1980s and then moved to a post-doc at Princeton in the 1990s. He then moved to a faculty position at the University of Massachusetts Amherst and then to a faculty position at the University of Texas at Austin. The last time I saw him, he was a professor at the University of California at San Diego.

Hogan has spent a total of 14 years doing math.

In that time, he has published about 100 papers.

If you want to get something done, you don't do 14 years of math. You do four years of math and two years of post-doc. (And that's if you want to get something done. If you want to spend your life doing math, you do four years of math and 14 years of math. )

The reason for this is that math is a very hard subject. The reason for this is that math is a very hard subject.

A mathematician's job is to take a very hard subject — say, differential geometry or mathematical logic — and make it easier to understand. If you want to get something done, you don't do 14 years of math. You do four years of math and two years of post-doc.

The reason for this is that math is a very hard subject.

It's also very difficult to understand.

And in the last several years, Hogan has become a specialist in something called "time travel."

The math is easy, but it's the content that's hard.

Let's walk through a couple of examples.

The first example is a famous one. In the late 1980s, a physicist named Roger Penrose showed that space is not Euclidean, as was assumed for over 2,000 years. Instead, space is curved. This is a very important discovery, but it's not as exciting as it sounds. A curved space isn't very different from a flat space. You just have to decide on a particular direction, and then you have to understand how the distance between points changes with that direction.

The second example is just as important, but it's much harder to explain.

The universe is a four dimensional object. In fact, it's the four dimensional object that all other three-dimensional objects are attached to.

What does this mean?

Well, it means that if you draw a 3D object, such as a cube, it will look the same no matter which direction you look at it from. That's because the cube is actually a four dimensional object, like a sphere. All cubes look the same from any direction. So, if you can draw a 3D object, it will look the same in any direction.

However, if you
