Modulus

Stiffness

Young's modulus

Stiffness variance

Just a little stiffness. That's all.

That's not guessing. The child has a fever, headache, stiffness.

You may recall that this percent sign is the modulus operator.

Addition, subtraction, times, modulus division etcetera, etcetera and to save some time

First, Alice and Bob agree publicly on a prime modulus and a generator.

Take a number, raise it to some exponent, divide by the modulus and output the ramainder.

like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

It's an observation with obvious medical applications in humans as well, but it's also relevant in a broad sense, I think, to the design of prosthetics, soft robots, basically anything where changes of shape and stiffness are important.

So if you're ever thinking about the issue of compliance, when we're talking about stiffness, think about these curves and the fact that where the slope is tells you how compliant something is, and that arteries are going to be more compliant than a stiff pipe, certainly, but less compliant than the veins.

This painting is often compared to an early renaissance painting by Raphael's teacher Perugino The Giving of the Keys to Saint Peter and you can begin to see here in this early work by Raphael indications of what we understand now as the high renaissance style as opposed to the kind of stiffness of the 15th century of the early renaissance.
