And recall that what we were talking about was the following, that there were several kinds of phagocytic cells. Phagocytic cells are cells that chew up other things, both macrophages and even more frequently, dendritic cells, many of which hang around lymph nodes by the way... |
https://ocw.mit.edu/courses/8-04-quantum-physics-i-spring-2016/8.04-spring-2016.zip | PROFESSOR: We have to ask what happens here? This series for h of u doesn't seem to stop. You go a 0, a 2, a 4. Well, it could go on forever. And what would happen if it goes on forever? So if it goes on forever, let's calculate what this aj plus 2 over aj as j goes to infinity. Let's see how the coefficients vary as y... |

https://ocw.mit.edu/courses/8-01sc-classical-mechanics-fall-2016/8.01sc-fall-2016.zip | Now we're going to analyze a more complicated example of drag forces, where we have an object falling in a gravitational field with gravity. We have a resistive force. And this is an object in air. And so our model will be for the resistive force that it's going to be proportional to the velocity squared. Now to get it... |
https://ocw.mit.edu/courses/7-014-introductory-biology-spring-2005/7.014-spring-2005.zip | So today we are going to continue where we left off last time talking more specifically about variations on the theme of life. And last year I tried to do this lecture using PowerPoint and it was a total disaster so I'm going back to the board. You will have the PowerPoint slides. They'll be on the Web to download to ... |
https://ocw.mit.edu/courses/8-04-quantum-physics-i-spring-2016/8.04-spring-2016.zip | BARTON ZWIEBACH: --that has served, also, our first example of solving the Schrodinger equation. Last time, I showed you a particle in a circle. And we wrote the wave function. And we said, OK, let's see what is the momentum of it. But now, let's solve, completely, this problem.

https://ocw.mit.edu/courses/8-01sc-classical-mechanics-fall-2016/8.01sc-fall-2016.zip | We would like to now apply the momentum principle to examples of recoil. So recall that the momentum principle is that the external force causes the momentum of the system to change. Now, this is a vector equation. So for example, if the external force in the x direction is 0, then the momentum of the system in the x d... |
https://ocw.mit.edu/courses/7-014-introductory-biology-spring-2005/7.014-spring-2005.zip | I just got the feedback from the one minute things just a few minutes before class, so I think I may defer commenting on the couple of them until the beginning of next lecture.

https://ocw.mit.edu/courses/8-04-quantum-physics-i-spring-2016/8.04-spring-2016.zip | PROFESSOR: So we go back to the integral. We think of k. We'll write it as k naught plus k tilde. And then we have psi of x0 equal 1 over square root of 2pi e to the ik naught x-- that part goes out-- integral dk tilde phi of k naught plus k tilde e to the ik tilde x dk. OK. So we're doing this integral. And now we're ... |
https://ocw.mit.edu/courses/8-04-quantum-physics-i-spring-2016/8.04-spring-2016.zip | PROFESSOR: What is a Rydberg atom? Well, it's a-- an atom can be a Rydberg atom if the outermost electron is in a very high principal quantum number. That's a definition of a Rydberg atom. The last electron is an n-- little n, very large. Now that is very interesting because when that happens, Rydberg atoms-- when that... |

https://ocw.mit.edu/courses/7-012-introduction-to-biology-fall-2004/7.012-fall-2004.zip | As I'm going to argue repeatedly today, biology has become a science over the last 50 years. And, as a consequence, we can talk about some basic principles. We can talk about some laws and then begin to apply them to very interesting biological problems. And so our general strategy this semester, as it has been in the ... |
https://ocw.mit.edu/courses/3-320-atomistic-computer-modeling-of-materials-sma-5107-spring-2005/3.320-spring-2005.zip | PROFESSOR: So what we'll do today is really switching to the computational description and characterization of thermodynamic properties.

We will demonstrate that the total mec... |
https://ocw.mit.edu/courses/8-01sc-classical-mechanics-fall-2016/8.01sc-fall-2016.zip | So suppose we have a point mass particle of mass m moving with a velocity vector, v.

But I sense that there's still some of you who have not yet come to terms with crystallographic directions and planes, and you feel a little bit awkward in distinguishing brackets around the HKL and parentheses around HKL. And there are some people wh... |
