The Lumpy Universe with Prof. David Kaiser
This conversation with Prof. David Kaiser, who teaches physics and the history of science at MIT, covers a vast timespan, from the beginning of the universe to the present day. Prof. Kaiser explains that inflationary cosmology helps connect our understanding of quantum fluctuations-what he calls the “jitters” that particles undergo at subatomic levels-to the irregular distribution of matter in the universe. What’s most exciting, he says, is that simulations based on inflationary theory produce predictions that closely match detailed measurements of the cosmos. Later in the interview, Prof. Kaiser discusses how he teaches his course on 20th-century science, seeking to demythologize Albert Einstein (“He was no Einstein as a young person!”) and examining the historical context of the development of nuclear weapons as portrayed in the 2023 film Oppenheimer. He hopes his students will learn to see science not as happening in isolation but as a product and producer of historical events and cultural changes. Lastly, he discusses what he’s learned from his years of teaching the course, and in particular how he helps students who are anxious about writing papers to overcome their fears.

    And you still cannot add new/different genetic/biological features during procreation. The only sets of DNA & RNA that can be used is provided by two donor sets of DNA & RNA. So biologically any ancestors modern man had, had to have all the possible DNA & RNA code we see exhibited today already. Which most likely would've occurred before life made it to land and would've survived throughout the time of the dinosaurs. It'll be interesting if we find mammals that existed in the ocean at the same time we started seeing fish or something like that.

    >+I respect your work mate. TA is all well and good but I find it truly baffling that all major crypto youtubers just look at pure TA and completely Ignore the bigger narrative of why BTC Is dumping and why the future outlook might not be as rosy as it seems. It's kinda irresponsible to ignore the fact that each ETF launch so far has caused a major dump at the peaks of BTC.. We were already on shaky footing with historically low volume and almost pure whale dumps, narrowly avoiding a long-term bear market.This is the worst possible time in history to Invest as so many don't back up their crypto assets...more emphasis should be put into day tradiing as It is less affected by the unpredictable nature of the Market..I have made over 4btc from day tradng with Murray Henderson, insights and signals in less than one week, this is one of the Best medium to backup your assets incase it goes bearish.

    In Germany computer science is named INFORMATIK. I think the german term is misleading. As it translate to information science. To me information science should be about the also for computers but also many other fields basic principle of IPO (Input, processing, output). Whereas computer science should be about the tools to process information with computers. I.e. data structures, algorithm and computers plus peripherals. Also I don't recommend to use PYTHON to teach computer science. I would recommend C and Assembly language to understand the very core of data processing. JMHO. Also it might be known that currently Python ranks as the most unefficient programming language based on a recent study. And as everybody should be aware also in regards to greener tech... EVERY SINGLE BIT COUNTS. AND EVERY WASTED CPU-CYCLE adds to the pollution.

    Well, you keep clear of, or bear at angle to beacons in fog. Those with familiarity to mountain scenes like the one shown, DO spend very conscious attention to navigable probabilities in EVERY direction. We immediately make cognitive maps. Intact brains are FAR more interesting than lesioned, damaged brains. Psychology was attractive for THIS reason. The evasive men in a mens'group were disgusting, while the schizophrenic guys who reported their feelings to me as i drove them across a distance, part urban, part rural, were so much MORE interesting. We were essentially mapping and navigating socially, with the deceptive supposedly "intact" very damaging socially to others, and so, to themselves, while the paranoid isolated were very naturally, intuitively, eager to be functional, adept, normal. We all, if interested in learning, follow the prof's assertions about good experiment: attentive to the, or any, independent variable. This is the difference between those whose brains attend to the spatial-like recording of real relationship for distortive, manipulative purposes, and those who explore to develop accurate prediction, the JOB of brains for well over 1/2 Billion years. I spent a decade experimenting with the free behaviors of free wild, self-willed nonprimates, to find noninvasively the different usages of senses which anatomically vary from ours. I was not so much shocked as exhilarated at their intelligences, compared with our quite deceptive and manipulative taxon. You guys may not know that pretty much the best, MRI machines in the US were mostly used for medicine, with research minimal and confined to late night & early am. This was due to the focus on perceived value. value being the medical intent of fixing everything. That drives the evaluation of cost, etc. and the resistance to, basic research. European experiment was much more copious, until after 2010 about. And pure rectilinearity is not common or ,finally, useful in nature. Assessment of verticality, yes. I watched the pleasure of predators, whether cursorial or ambush, in estimating vectors, and adjusting their own anticipatory response. The very anatomy of eyes varies from ours, with foveae useful for their purposes, differing from ours. That means salient information differs. We should and do have both evasive and convergent utility, and so regions where proximal topologies would be selected for. But neocortex has six layers highly stratified, reaching axons to useful distant regions, but still speaking and listening, axon/dendrite, within the region having those 3 to 6 layers of cortices. That is a source of conflation in the experiments referenced in this course.

    She had referred to the hallucinations of, SPECIFICALLY, eyes and mouth, when surgeons stimulated neurons in FFA. While upside down recognition was reduced in fMRI testing, it was of recognition of individually varied faces. Babies, of course begin with a prosopagnosia, first responding in an evolutionarily useful way to ANY face, while developing specific (familiar, remembered, known faces using some smaller-scale pattern recognition, OR feedback from other areas connected through associational - secondary - cortical regions.) differential responses. This pulls in regions that stimulate both neurohormonal and endocrine response. Whether pleasure or some form of noxious response to both associations and to minor FFA variances- different neurons send totally different dendrites becomes vastly important, even if BOLD signal might total up insignificantly different.

    What the professor says is not quite true. The experimentalist that proved the Bell Inequality showed that Quantum Mechanics can have local hidden variables, but then it must be non local, as in the case of the Pilot Wave interpretation. In this interpretation particles are real and are guided by real pilot waves. The particles have real positions and trajectories, and only the initial conditions are uncertain. The Pilot Wave interpretation is known to predict all quantum effects.
