Tricky like a raccoon.

We want to know how much longer the new route is.

That can be tricky here at Monte Carlo.

Then comparing them with observations of real universe is an even, trickier yet.

R is make sure you understand your working directory and set your working directory.

It's a creative activity. It's fun stuff.

Only raccoons could be this tricky.

1, 1, 2, 3, 4, 4. Here I have two 1's and I have two 4's.

That was tricky.

Right?

We can ostensibly measure Hubble constant.

You can do this with any Redshift survey, and it, it was indeed done so.

In producing such a cause effect chain automatically is your homework.

An easy way to think about multiplication or timesing something is it's just a simple way of doing addition over and over again.

R is a little bit tricky.

Which is like in scalers, taking two times the inverse of two a half, with getting the result one, and here's the identity matrix.

In the meanwhile, let me conclude the first part of my show by doing something a little trickier.

Weinberg was also the original inventor of the pressurized water reactor.

I want to show you, real quickly, just a minute of Rockett's Tricky Decision, which went gold two days ago.

These tricky little levels were composed by Peter, Simon, Genevieve and their father Ian Wadham. They use traditional playing rules. Enjoy!

Sometimes we measure distances not to individual galaxies but clusters to which they belong and that's were we can hour its measurement over a large number of galaxies have improved the corresponding measurement for the entire cluster, so measuring distance to galaxies is very tricky as we probably recall from the various chapter, but there is another way in which we can measure peculiar velocities and that is from red shift surveys themselves.
