[JONATHAN WOSEN]: So the idea behind any vaccine is to introduce some piece of a virus to your body so you can mount an immune response. And then your immune system sees those fragments and learns to respond to it.

[ALBERT BOURLA]: You do things in parallel. Research, trials, manufacturing, and distribution.

[MIKE MCDERMOTT]: So if we think about how long we would take to build our manufacturing network, typically that would be a two to three year process. We shrank it down to about five months.

[NATHAN VARDI]: There are some important reasons why messenger RNA was appealing for developing a COVID-19 vaccine. First of all, the virus itself is an RNA virus. So it lent itself to this technology.

[PHIL DORMITZER]: In an RNA based vaccine, you simply inject the instruction set that teaches your body how to make a piece of the virus.

[LAURIE GARRETT]: This is going to have a huge impact down the road.

[FRANK SNOWDEN]: It's wonderful…. What's happening is an extraordinary scientific breakthrough.

Calculating kinetic energy | Modeling energy | High school physics | Khan Academy

In this video, we’re going to talk about kinetic energy, and we’re also going to think about how to calculate it. So, you can already imagine, based on the word “kinetic,” which is referring to motion, that this is the energy that an object has by virtue …

Worked example: Differentiating related functions | AP Calculus AB | Khan Academy

The differentiable functions X and Y are related by the following equation: the sine of X plus cosine of Y is equal to square root of 2. They also tell us that the derivative of X with respect to T is equal to 5. They also ask us to find the derivative of…

RC step response 1 of 3 setup

In the last video, we looked at this RC circuit, and we gave it a step input with this step source. A step from V naught up to V s, with a sharp change right here at t equals zero. We sort of took an intuitive guess at what this voltage looks like—here’s …
