Secrets of the conch shell and its toughness

The Massachusetts Institute of Technology is an independent, coeducational, privately endowed university in Cambridge, Massachusetts. Our mission is to advance knowledge; to educate students in science, engineering, and technology; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place.

The MIT YouTube channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.

After all, mother nature still has a lot to teach us.

[Xzacher]

All you had to do was pull the string and ask its secret...

[amsterdan]

That's really cool, but I don't know if it would make optimal materials for helmets. The secret to a helmet is to fold and crunch in a way to dissipate the enourmous quantities of kinetic energy from the bullet. Something like this would not deformate, and all the energy would be transfered to the persons skull. The bullet may not penetrate, but the energy would be more than enough to kill the wearer, wouldn't it? Otherwise is great to see technology beeing discovered and created in real time. I wish I could study at MIT, it seems that all the newest technology in robotics and other areas is beeing created there!

[somerandom]

Technology from nature...
Amazing...

[syedbasha]

Great..! I wish I could study at MIT..

[domenicolattuca]

Very interesting, but would not it be useful in other fields?

[gregfeneis]

Varying grain direction per layer is what makes plywood so good, a 19th century invention. Why are we just discovering this for 3D printing?

[RexusKing]

So basically the same idea as plywood?

[SquarePirate_]

The problem is not penetration, it's the force of impact. Something has to absorb all that kinetic energy and it's usually our body.

[gengenone]

Seems MIT never made a quilt or great french pastry.Think of cracks like air temp or trying to stay warm with the least bulk. Samething as the shell. Twists, turns and folds.

[yutuniopati]

And of course the first one who will use it is the military, as always...

[flybird]

So this one wont break like the one in the lord of the flies?

[alexgehl]

I wonder if this structure could reduce the brittle properties of carbon fiber...

[marglesjerkz]

I have a female conch shell and wants to sell it

they fight for not sure on intention (wich intention was the middle wich
is to swap organs of some type of other humans for middle aged organs)
so they both become enemies or aggressive (the external humans not
nightmares)

do not eat glorious beings of under the sea or underwater you can eat
the nonglorious ones such as primitive fishes with no limbs und dumb or
offerings oisters includy part of the regrowing part of glorious ones,
you tell this to all japanese und mongol und plinesian, additionly
trickster may be come as food who was posting dat video since is a male
person spread the word

you can cycle 10---20 days the utilization of corn food perhaps 5 days
on r5 days off wich can also include some fat cyclings of animal fat
harvested alive off from pigs
then also 1.2---1.46 times mass multiplyer of muscle mass every 10
----20 month up then 10----20 month for downward cycle of weight (for
example going from 60 kg muscle upward to 88 kg muscle plus some more
fat within duration of 10----20 month (enough sleep is required plus
eating, then back to 60 under additional 10----20 month)

need 6---10 days of rest und low exersice during building after every
30---45 days of exersice

1/3 of body weight 1 day then day offf another third of weight of
muscles 1 day then 1 day off then the last 1/3 of the body weight is
trained und one day off then again the first 1/3 und repeating as
described at the begining of this sentence

need to list trainings for days like a calendar changing the pages (6
page train activities perhaps 18 or more for the way the body is
exersiced but there are more ways of training muscle minimum 6) include
on this calendar wich turns around the restfull days also

apply one series of warmup for some muscles or lung train 2 hours after
eating enough, 3-6 series per muscle (group)

eat 2-5 times a day perhaps more times occasional chocolete or something
in small ammounts with 3 major feasts or one feast und 2 smaller with
more eatings during some times but only small ammounts (including some
glucse with simple to digest amino acid und protein

See work America is not full of idiots

Who wants to buy this conch shell? I have a female
