After 8 seconds it said "This film is not presented as fact." So I did not watch the rest. Correct. I am not interested. But if anyone provides reliable scientific evidence about progress in our understanding of gravity (and/or anti gravity) I would be very interested. Warning: Straw man ahead: *) Replace alien technology with "magic", "psychic powers", "spirits", "life after death". The scientific content would be the same (zero).

https://theconversation.com/explainer-why-are-we-afraid-of-spiders-26405 I’ve been wondering a small bit about the irrational fear evoked by spiders and snakes. Some people say there may be an evolutionary component to it as a few of these creatures can potentially be deadly. But our visceral response to them seems to be far more excessive than the actual threat they would have posed throughout human evolution. Humans obviously have a limited capacity to empathise with animals. We can anthropomorphise our pets and we might admire animals in the zoo. But as the philosopher Thomas Nagal pointed out, “What is it Like to be a Bat?”. In other words what is the sentience of these creatures like? They can’t just be inanimate robots as they display complex behaviour. Perhaps they live in a barely self-aware oneiric sort of existence that will be forever unknown to us. Some exotic creatures may possess a mind so “alien” to ours that it becomes repulsive when we try to project a degree of consciousness onto it. So might the creepiness of spiders and snakes be more of our instinctive reaction to their unfathomable psychology rather than the actual biology of them?

The limitation of that study is that the virus had to be pre-treated with the surfactant to become less virulent. In the follow-ups I also only see co-treatment or in vitro assays. It is unclear how you would employ it in an in vivo situation. If the virus is already in, there is a good change it won't do any good (or you may have pump so much into the patient that it becomes harmful). It is sad that folks forgo the health information provided by the same administration.

That is not true at all. In Africa different societies existed ranging from the nomadic groups you mentioned to fairly large empires. One of the best known is the Songhai empire (15th-16th century). Among the cities within that empire Timbuktu and Djenne were powerful commercial entities. There are of course far more examples (Aksum, Kingdom of Ghana, Abyssinia to name a few). What I am saying is that the view of Africans as nomadic tribes is Westernized colonialist view that is not in line with actual history and I would urge caution to build any generalizations from this level of misinformation. And before we get to that, in the New World, it is the same, indigenous people had built complex societies in nations, which, while different than their Western counterparts, were highly complex political and societal system and had various levels of urbanization that were not too different from certain Western nations of the same time. Of course the situation shifted when we come closer to the time of the Atlantic slave trade but it is erroneous assumption that all there was were nomadic (and often also assumed to be primitive) tribes.

Well balance should still be factual. I do not know De Havilland but Parsons received engineering training at an engineering firm after his studies in mathematics. I do not want to derail it further but if one needs to dig back two centuries and still not find plenty of examples it does somehow indicate the rarity of such achievements, no? Meanwhile there are countless unnamed, non-famous with training labouring away to provide all the basic information we have on this and other diseases (at times, at personal risk) which are summarily dismissed because obviously what they do is too mundane and boring. Instead, we long for stories of the untrained underdog saving humanity by having flashes of genius that are misunderstood by those actually working on it. It sure is a great Hollywood story but it sure ain't what's happening.

She was studying at a time where it was generally prohibited for women and ultimately produced a dissertation. She also taught at university in her 20s. I.e. her whole career was rather academic (not to mention private life, being the daughter of a mathematician).

Citation needed. The piano? Designed by a piano designer. Predicted by a computational chemist. First manufactured by a chemist. First theorised by a physicist. Further refined by other physicists and chemists. Manufactured by physicists and chemists. Invented by two German engineers. Started by software engineers and money men. All the advances you mention were made by experts in their field. (You might have been able to find a couple of examples from mathematics and astronomy; they are among the few areas where outsiders do occasionally make significant contributions.) Not a single one was the result of some random person with no expertise in the subject making uninformed suggestions. But this is just another off-topic hijack by the conspiracy minded. So we will leave it there.

But the James Bond movies would suffer...

B Lazar has been making these claims for over 20 yrs. I distinctly remember seeing him on TV shows dealing with UFOs in the 90s. Wouldn't the simpler explanation be that he has no academic records from MIT/Caltech, rather than the Government 'scrubbed' them ? And what makes us so special that they'd want to play 'cat and mouse' games with us ? You'd think they would explore the galaxy, not anally probe Americans from southern states.

You are still not clear about what you want to do or what you expect to happen. Have you yet read about blocking calls and how they work in this case? Here is an ugly attempt*. I guess that you need cpu_percent(interval=1) to return non-zero for the current process. So I create one thread doing some work while sampling CPU load. import psutil import os import random import threading pid=os.getpid() # current process # define some meaningless task for the CPU def sorting(): print("sorting()") for v in range(100): sequence = [i for i in range(20000)] random.shuffle(sequence) sequence.sort(); print("sorting() done") print("start thread") psutil.Process(pid).cpu_percent(interval=0) th=threading.Thread(target=sorting,args=()) th.start() while th.is_alive(): print("CPU usage:"+ str(psutil.Process(pid).cpu_percent(interval=1))) print("all done") The system did not bother to produce an error message? Out of memory error? >>>sys.maxint 9223372036854775807 (Which is 2^63 - 1) Not necessarily the same on all versions and on all systems. Here is a link: https://lmgtfy.com/?q=Is+there+any+size+limitation+with+integers+in+python%3F *) have limited time, this is a quick hack that runs, it is not necessarily giving any meaningful measurements.

It's not intuitive. Another one not intuitive to me is cold bleach, it seems, bleaches better than warm or hot bleach. Edit: Lower concentration increases contact time so that the surface of the microorganisms protein coat is not denatured too quickly such that it prevents more of the alcohol penetrating deeper into them. Superficial denaturing may just initiate dormancy.

Nitrogen can’t accommodate 5 covalent bonds. It can and does form ammonium salts, with the halogen acting as a counter ion.

Experts are seldom thrilled by suggestions made by outsiders, but outsiders bring most progress. Yes, ideas are badly scarce,. And on the Internet, you find the same people as in companies, with the same skills but not as grossly misused. Think at the Steinway. The production of fullerenes or graphene. The chipcard. The contactless chipcard. Many solutions for the Fukushima disaster. Paypal. SpaceX. Tesla. And so on and so forth. Waiting for experts, or worse for known experts, to solve everything and bring all innovation is a recipe for stagnation. It's also contrary to observation.

Ah yes, the complete absence of evidence just proves how deep the conspiracy goes. (Blimey. I thought you were joking. You’re serious!? Wow)

Strange, don't lie to favour your misconceptions.
