You get in a time machine.

My machine!

EXPERTS SAY TO FlND OUT IF THAT'S HAPPENED TO FlND THAT

Remember that r is measured from wherever you are, to the center of the earth.

It's not going to change r that dramatically especially in turns of the percentage

Well, finally my atom smasher was ready.

Even if you had invented a time machine, what of it?

In fact, the sphere itself is the set of all points in three dimensions that is exactly the radius away from the center.

Caroline Lavelle casts a spell on cello

That sound was just so beautiful, the sound of Doc's voice and the rippling groove of the banjo.

The workhouse is a machine for grinding rogues honest.

With that out of the way, let's just apply this radius being 7 centimeters to this formular right over here.

Clarence I would rather be able to play an instrument again There's so much joy and things I could get from playing an instrument and performing.

So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine.

Travelling through the fourth dimension will never be a walk in the park, but it turns out there is a surprisingly straightforward way to do it.

This r isn't that different. It's a little further than if you were at the surface of the earth.

Where r is the radius of the sphere.

Or really r is the center of object to the center of earth. The center of the earth represents most of the distance here.

Phone Yeah, well so when was the last time you used the photocopier?

I knew I had to take a banjo with me to China.

If I had a time machine, I'd visit Marilyn Monroe in her prime.

In the 1980s in the communist Eastern Germany, if you owned a typewriter, you had to register it with the government.

I could get from playing an instrument and performing.

That time turner is fantastic Hermione, you should keep it forever!

I bought a banjo, I threw it in my little red truck and I traveled down through Appalachia and I learned a bunch of old American songs, and I ended up in Kentucky at the International Bluegrass Music Association Convention.

So I picked up my banjo and I nervously played four songs that I actually knew with them.

Phone Did you complete that thing about a month ago? That photocopier training?

The circumference is 2 pi times the radius which is equal to 2 pi and in the previous video, we figured out the radius was 6 m

I just put a can on a copier and kept enlarging it until I got the size I want.

The designer in a bottle factory can't move bottles faster than the machine can.

I would rather be able to play an instrument again than walk.

You say It seems to me if you held the drill this way first, it would work better and that's what I found.

Time travel movies often feature a vast, energy hungry machine.

I like to imagine how a space ship might some day be able to take advantage of this spectacular phenomena.

We've identified the 50 most important machines that we think it takes for modern life to exist things from tractors, bread ovens, circuit makers.

And we've made a Wayback Machine that you can then go and see old websites kind of the way they were.

It reminded me a lot of the talk we heard this morning, about this operating room machinery that was designed specifically for Africa.

like lining up cars around the room and staring at the washing machine and eating anything that came in between.

and I said I'm playing the cello and I'm doing a bit of singing, and he said, Oh, I sort of play the cello as well.

So when new machine is coming into industry, as instead as you're working 5 hours a day, you work two hours a day.

We've identified the 50 most important machines that we think it takes for modern life to exist things from tractors, bread ovens, circuit makers.

But what atrazine does is it turns on an enzyme, the machinery if you will, aromatase, that converts testosterone into estrogen.

The steam engine and the other associated technologies of the Industrial Revolution changed the world and influenced human history so much, that in the words of the historian Ian Morris,

Now, to find the volume of a sphere, we prove this or you will see a proof for this later when you learn calculus, but the formula for the volume of a sphere is volume is equal to 4 thirds pi r 3.
