How to pronounce “ellipses” in English

is the amplitude of these gravitational waves from inflation.So it's all ellipses.

with the Earth at 365 days.And so these are two ellipses.And what they started calculating is, can we bring this back to the Earth?

due to gravity. This is exactly what Newton was able to use to predict, for example, that planets move in ellipses.Kepler had already established the planets do move in ellipses.Newton explained to us why.

So what do you see visually normally?I think normally you see-- I think it is ellipses.Right? What does it mean to you, visually?

Newton explained to us why.If you have planets moving under an inverse square law of gravity, they will move in ellipses.So this was a huge triumph for theoretical physics and for observational astronomy in their early days, a quantitative relationship that predicted something that

You have that up front.So the point of what I want to be here for today is to tell you the part that comes after the ellipses, "Just Because My Husband'sa Woman," dot-dot-dot, "Marcy's Side of the Story."

at least for a simplified solar model, solar system model.And if you now solve those differential equations, you get ellipses, and you've explained why those orbits are ellipses.And I think there's something very satisfying about that kind of explanation.

from above, we would notice two other interesting things.First of all, the orbits of all the planets around the sun are very nearly circles. Officially, they are ellipses.They're not quite circular, but they're awfully close to being circular.

You can use this equation, plug it in, relate it to the force example that we have in F equals ma, and then get a relationship for the accelerationdue to gravity. This is exactly what Newton was able to use to predict, for example, that planets move in ellipses.Kepler had already established the planets do move in ellipses.

It looks not like what we're doing.No black cats allowed, snowboarding, no strollers on the escalator, no inclined ellipses beneath mysterious shadows.

And so if you cover yourself in carbohydrates, you're shielding yourself from antibodies.And we have different areas-- like this red area right here, we know that that's what this person here is showing as these ellipses.
