Outstanding lecture.  Thank you MIT for making this public.

Excellent lectures--excellent lecturer! Bravo, Lorna. Thank you MIT.

very very interesting... finally youtube made a proper video suggestion. Hopefully there is enough math that follows up to allow us to play around with our own ideas.

Wish I could feel/interact with those samples. Every innovation lab should have samples like that to consider the realm of the possible in product design.

This information is pretty generous of you thank you

It is damn that I can't have opportunities to sit down in his class!

Is it possible to use soft tissue scaffold several times in a tissue expansion process to thiken the skin or would you rather use a thicker soft tissue scaffold just 1 time?
For example, lets say a woman would use a soft tissue scaffold for breast reconstruction after a mastectomy, just hypothetically... lets say she would like to expand her skin breast tissue to be able to have 4000cc breast implans... just to get an idea, of what soft tissue scaffolds could be able to do or not do...
She'd need 2 pair of tissue expanders. The first pair of like 800cc overfilled to reach up to 2000cc and then she would exchange the expanders as she reach 2000cc volume with a new bigger pair of breast tissue expanders that would be able to be over filled to 4000cc volume, her desired volume.
Now.. of 2 options which would you recommend?
1. 1 thick scaffold.. Would you use just 1 kind of thick soft tissue scaffold. how thick would you have it to be able to stretch her skin to the volume of 4000cc?

OR
2. 2 layers of soft tissue scaffold each inserted together with the pair of expanders. 1 layer of soft tissue scaffold together with the first breast tissue expanders, and then insert 1 more soft tissue scaffold as the tissue expanders implants are replaced with the bigger expanders that can reach 4000cc?

And... one last question... is it hard to remove the scaffold from the expanders? the scaffolds become one with the skin right? or is it more like a capsule surrounding the implants? is it okay to use scaffold in an expandable breast pocket if the scaffold is expandable? or would you use the tissue scaffold when permanent implants are set in place, after the expansion of the breast tissue has been achieved?

Dear mam, as u have explained the limits for the relative density of polymer foams is 0.2. What should be the limit for relative density of honeycombs?

[usamarehman]

a o a can any one help me to derive differential eq. of tchebycheff polynomial of 2nd kind Sn(x)

[songy]

I want these books. Where can I find it?

Put the title of the course in the title of the dang video.
