depends on where you started, if it was from the outside in I think it would be extremely painful as your nerve receptors receive signals that things are starting to go missing and want you to fix it. if it was from the inside out you would definitly be dead before it start to hurt too badly as we don't have next to any pain receptors internally

No. You would notice. We have atoms gone all the time. We're huge atom shredders. Colossal ones, honestly. lol At that level things are not really sensible. It's a delicate field and additions are just not a small thing by any means. The field of micro biology I guess this would fall into, I'm telling you you're not gonna feel a thing in this context. If you have atoms interacting, changes will certainly go on and they'll unsettle situations. If you're inserting something to remove atoms that's gonna change things. Adding and taking away atoms makes a difference. In practical terms, you won't think anything is going on. You will be the poster boy of unphasedness. lol Based.

Yup. Inside-out? Some blood vessel would burst, you'd bleed internally without pain until you lose consciousness and die. Then you'd slowly disappear, while everybody around you is wondering WTF is happening.

If it's outsiide-in? Then you'd get extremely hot as a burning sensation pours over your entire body. You'd probably also lose blood very quickly at this point, but not before excrutiating pain. Best case scenario, for some reason you don't lose blood, and you have a few seconds/minutes as a screaming skeletal muscle anatomy lesson.

How the fuck do they know what's happening inside of living things? Particularly with neurochemistry. You've got, let's say, a working brain. It's full of juices. You've got a science lab. How do you go about separating which juices are which and determining how they behave in the living brain?

Graphene is very interesting nanomaterial for me. I heard that grapheneis widespread and used in electronic. It has next characteristics Carbon > 99, 6%, Thickness (nm): < 3.0 , MB surface area (m2/g): ~80, Density (kg/m3): 2,2, Bulk density (kg/m3): 120, Electrical resistivity (Q.cm-1): < 0.15. I think you need to find graphene in special laboratories like it http://mstnano.com/products/graphene/

>>How do you go about separating which juices are which and determining how they behave in the living brain?
It takes a really long time and a lot of work and most of the time you will be wrong or overly simplistic in your interpretation of what is going on. Serotonin for example was so named because they believed at first its primary function was modulating the consistency of blood serum.
For the specifics though, the way they tell which neurotransmitters affect what is by looking for ligand receptors at the synapse. The neurotransmitter works by being a 'key' for a specific molecular lock on the receiving cell, which initiates its action potential to propagate a shifting ion gradient through the dendrite. Then, they follow the trail of that neuron chain's axons until they get to something that's a muscle or sensory cluster (or backwards, to a specific region of the brain) and then end up saying something like 'these neurons are part of a pathway connecting this behavior/sensation to control from this brain region, modulated by this neurotransmitter.' If you noticed this is not much different than the room of blind men describing an elephant by grabbing different parts, grats, you've been paying attention.

Ok so we have this great technology called electrolysis. And we can use it too to purify water and create hydrogen. So I was watching a YouTube video and it said current estimates suggest turning 1% of the Sahara into a solar farm would produce enough power to power the globe. The only problem with that is they could only make power lines for neiboring countries and it would lose 10% of the power if some how we were able to get power cables all the way to Europe.

Well here's a fricken idea. Why don't we turn the Sahara into a solar farm, and use all of the energy to purify water supplies and turn it into a major exporter of hydrogen? It seems like the Sahara is an untapped resource for comparing the worlds oil crisis.. and additionally it was speculated that the energy absorbed by the solar panels would decrease the total temperature of the Sahara introducing more rain and possibly vegetation to an otherwise dry ecosystem.

Seems like an over all win win to me. What do yall think?

I have come up with a method. I just lack the technical know how.
You would need basic laser technology, but modified so that the laser gas is generated from the surrounding air with an oxygen concentrator. If you could manage to push enough energy through it, you could have a cutting laser. Now, there are ways to magnify the laser into more of a blade, but the issue is a laser just goes on and on, it doesnt stop. So you would need a way to stop it. I suggest a telescoping heat resistant pole that extends when activated, at the end of which is a circular beam trap. Instead of one laser, this design would call for a circle of beams around the inner pole which would make a wider blade. The inner pole could also likely be used to block. The lasers would only be for heat.

But then, maybe it would be of help if one made the total definitive top of the layer on the outermost exposed edges to give those planes that are left exposed but flattened, would it help to make only that specific part as frictionless as possible?
Or would it be micro-optimization at that point?

Let's discuss how we could update and redesign our global infrastructure and cities, as well as building new ones, in order to better utilize the latent global energy available. Thermal/kinetic/wind/water/solar energy into electricity, and built into our infrastructure and cities. Can we utilize biotechnology? Nanotechnology?

>What would be the hardest parts of this process? It is too costly to redesign the old? Should we just build elsewhere? Maybe even in space or other worlds?

>What should these new infrastructure/city designs be like? Are there certain geometries or naturalistic patterns we can mimic to make our structures more efficient at weight bearing, flexibility, etc? Something out of Stark Trek or the Venus Project? The word "ecopotia" comes to mind here.

>Can it be done before we succumb to environmental collapse in the next 10-100 years?

>What will have to be changed socially, culturally, economically for these changes to make a meaningful lasting impact on our world for the better?

So we're all familiar with the Moh's scale of mineral hardness, which is based on which minerals can scratch which. But I'm curious about the topic of mineral "toughness", which is based around how easily a given mineral will crack, chip, shatter, etc.

Apparently this is much harder to measure, however, and I can't find much info on this topic online. can anyone help me find a list of minerals / gemstones ranked by toughness, or something similar?

(pic related, jade is generally agreed to be the toughest mineral, supposedly)

I don't think you are as smart as you claim to be, since you would probably understand that most people won't blindly donate to a person who has only made rather grand claims and shown no proof for those claims.

I liked your writing style but I also think you have to understand it's not going to help you get money from people. it reminded me of Feersum Endjinn by Ian M. Banks.

I would love to read some of this compiled information of yours.

I think you might not understand that our modern society does not care about grand ideas for the sake of grand ideas. It's all about your ability to sell those ideas. Doesn't matter if it saves an endangered species, feeds thousands of familys, or ends corporate dictatorship, your wonderful ideas are worth nothing unless you can convince the powerful that they will benefit from it's implementation. And everything points to the powerful being egotistical and selfish, choosing consolidation of their wealth over the growth of others. It doesn't matter why they choose that, it is just the way it is.

You cannot just have great ideas and change the world, not any longer.

Not to mention, if your ideas were as great as you claim, you would immediately release them for the betterment of humanity and not try to extort a couple bucks from a bunch of stoners. If they are as great as you say, spam Musk until he saves us All.

I’m in a biochem degree, and I’m in my senior year (so I’d be graduating spring 2020). So far I’ve loved all my biochem classes, all the genetics and microbiology electives, organic chem, and I even wound up liking my basic physics stuff cause even though I wasn’t great at it or interested in it, I had truly great professors that I remember well and up till now I haven’t regretted a thing.

Anyway I’ve entered a point where I think I’ve Peter Principled myself. I’m in the first round of p-chem and it may honestly stop me from finishing the degree, just a semester and a half out from me finishing it. I had similar freak outs with basic physics, but like I said my professors were great, and both times I pulled a B+ out of my ass/hard effort. The troubling thing is I really like my p-chem prof too, and have no complaints about his teaching style or expectations or willingness to help or anything - I just honestly think I’m not gonna be able to fucking pass it. I did well in calculus, but it’s been 5 goddamn years since those classes. And the more time I sink into trying to get my head above water in this physical chem stuff the less time I have for analytical chem which is also no cake walk.

It’s hard to think that I might not be cut out for this, because everything I’ve done under the purview of the rest of my degree, including analytical chem and instrumentation and shit, I’ve enjoyed it and excelled at it.

Most people I talk to who have done shit like this say get out ASAP if you don’t love it. But I’ve loved all of it /except/ this class, and this may be the one to stop from getting the degree. I’m sure I’m just being petulant when I say this but it sucks all the more to think it’s the least biochem-y thing out of the whole goddamn biochem major that might knock me out of contention.

Anyway, I know I’m not the first person to struggle with p-chem, but I’m at a loss. I’m doing everything I’ve done in the past and more and I’m still projecting an F. So any advice from someone who’s gone through this? I’m obviously gonna push through the semester and do my best, but if I have to take it again I’m gonna be out of time and money, so idk what to do. What would happen if I had to quit this late in the race?

Firstly, does anyone have recommendations for an intro to combinatorics book that is good? Something readable but also worth the effort?

Second, if anyone could give me a rundown of what topics I need to be well versed in before getting into combinatorics, I'd love to check all those boxes first.

I took the class for a few weeks but had to drop the term for some personal reasons. I think we used a different book back then, but this is what the current professor is using.

Class title is "Combinatorics and Discrete Mathematics" - not sure how strictly on-topic the book will be as a result.
