But also how worms came to be the shape they are and why a bat can y into a rose bush without tearing its wings.

A structure has been defined as “an assemblage of material which is rent to sustain loads, and the study of structures one of the traditional branches of science. work of fracture (aka toughness) is the quantity of energy requried to break a given cross-section of a material Bonds - In Rodrigo Quian Quiroga's "Neuroscience Fiction" there is an often reported case of visualizing Jennifer Anniston (they used celebrities) and mapping neurons to see how the system works... Information in the brain is stored in what looks like a network map with a "key" if you're familiar with database programs. So there is a unique neuron that tries into trees of neurons in the visual cortex for images of the actress, tied to ones with 'Friends' (pun), her other movies if you've seen them, as well as auditory neural patterns that correspond with her name or or voice (way more complex but that's the gist from evidence I've seen so far). Now these can be flavored with different neurotransmitters with likeness or similarity as in Robert Cialdini "Influence" which would make sense since aspects of that person's neural trees could be similar and thus understood and resonate with your own (having common interests like you tubers, politics, hobbies, etc). It could be flavored with oxytocin as in love (Dr. Huberman had a video with love as a mapping function as well with loved ones been wired in close with an expectation of how long it would take to see them and the pain of losing them and not being able to find them). But there are also negative painful flavors that would keep them in the network but not the traditional one as they would be adversarial links or repulsive bonds or fractures in this case. So similar to chemistry one could make much broader and more diverseness links with not only other people but symbolic cues as well pertaining to social structures. Shells - In chemistry there are shells that enclose the nucleus or node in this case and get larger and more complex as one moves from the inner circle... It seems fitting that the S orbital has two spots that one could assign to the parents who usually give the greatest influences on the person's later social development... from there it's not as simple as there are possible siblings, and other family members moving out but that could be one repeating shell. Friends of different intimacy and setting in another though transitivity could draw them all together. Shells, for work, education, entertainment, exercise, region, politics, etc with different strengths and capping out around Dunbar's 150 bonds for known people at least though weaker bonds exist (especially in information flows). But it should also be noted that the metaphor doesn't hold exactly as the bond for various institutions of their own as shell connections that can scale into larger super organism/structures like companies, movements, nations, etc with organizational structures as well. The book incorporated a fair bit of math, but it was simple to understand. If you intend to use the principles of this book in your own life, I suggest taking notes in a separate notebook.That the study of structures and the way in which they carry loads incompletes-Sle, relevant and very boring indeed.

We might start by asking how it is that any inanimate solid, such as steel or stone or timber or plastic, is able to resist a mechanical force at all – or even to sustain its own weight. This is, essentially, the problem of ‘Why we don’t fall through the floor’ and the answer is by no means obvious. Strain is a function of the length of an object after applying the force, with its original length.The author's purpose is to introduce the basic principles of structural engineering in a way that leaves the reader with good intuitions about how structures work, an appreciation for how the field has evolved (and, in turn, how we've evolved with it), and optimism for what the future holds. This is a real personal statement written by a student for their university application. It might help you decide what to include in your own. There are lots more examples in our collection of sample personal statements.
