"Didn't do anything" is incorrect. Obama, for instance, https://www.thoughtco.com/obama-gun-laws-passed-by-congress-3367595 (Trump rescinded an EO limiting access for the mentally ill) Legislation is hard to do when you don't have the cooperation of congress. What would GW Bush and Trump's excuse be on that front?

The thing is when one is in the grip of insanity one doesn't know one is insane.

Disconcerting even when viewed per capita / controlled for population: https://www.vox.com/policy-and-politics/2017/10/2/16399418/us-gun-violence-statistics-maps-charts

For God's sake, don't ask us! Ask your dissertation director. It is the people who will be reviewing your dissertation that count! Generally speaking, while a master's thesis can be a "review" of other work, a doctoral dissertation must be original work- but that original work can extend previous work by others.

Saying "Now is not the time" because it's just after a mass shooting sounds kind-of reasonable. But when your country averages about 1 mass shooting every day, you essentially rule out any discussion. Was that the intention? It's quite a neat ploy, but surely people will see through it. https://www.theguardian.com/us-news/ng-interactive/2017/oct/02/america-mass-shootings-gun-violence

"Have you ever seen what a woman's face looks like after an acid attack?" No, I haven't and neither have you, as you say "I have seen pictures." "Do you know how many acid attacks have been committed in London since the first one occurred?" No, I don't know, and neither do you- as you say "Some give the number over 1000." "The exact number doesn't matter much." In a thread about mass shooting, that's the first bit you have got nearly right. But here's a heartening thought. The government just announced that it plans to do something about it by restricting sales of acid. http://www.telegraph.co.uk/news/2017/10/03/18s-will-banned-buying-acid-amber-rudd-announces/ That's because most people don't need access to sulphuric acid very often (and under 18s don't need it at all). Now, just as soon as the people of the US realise that the same applies to guns, these mass shootings might slow down a bit. Like they did in Australia. BTW, feel free to ignore me. But, if you don't respond to valid points, you are not taking part in a discussion (instead, you are soap-boxing) and you will get banned.

Regarding the argument that allowing people to carry guns can reduce the danger when some crazy guy (and/or terrorist) starts shooting people, as there is a mass shooting almost everyday in the USA there should be some good statistical data to support (or otherwise) this argument. So, of all the cases of mass shootings, how many were much less serious than they would have been because a member of the public was carrying a weapon? 10%? 50%? 90%?

That depends on the field and the policies of the institution. I have a master's degree in physics which was based only on coursework and the comprehensive exam that I passed to qualify for the PhD program (PhD qual required a higher score than a master's pass). Any individual program may or may not require original research for a dissertation. http://matt.might.net/articles/phd-school-in-pictures/

From those numbers: in the US, in 5 hours time, 7 people will be shot dead. We''ll have to wait 9 days before someone is shot dead in the UK.

! Moderator Note First, if swansont (or any mod/admin) is participating in a discussion, he doesn't actively moderate it (with some exceptions in Speculations, where the rules don't require as much judgement). He's not wielding any unfair authority to support his positions. I suspect instead he's using his knowledge of science as a working atomic physicist to support the explanations he uses. ! Moderator Note Second, it's abundantly clear you don't understand much of what you're defending, since you can't support it with evidence or make a testable prediction that anyone studying science could use to verify the accuracy of your claims. Science isn't about finding proof, it's about finding the best natural explanations, which are always the ones that have a preponderance of evidence to support them. Third, you've failed to support your arguments according to the rules of this section. You're also trying to drag our standards down rather than using more rigor to meet them, and that's not what you agreed to when you joined and said you'd follow the rules. If you wanted to test your ideas in a moderated science discussion forum, you shouldn't be pushing back so hard against the constructive criticism. Thread closed.

Ah, hang on guys, I've just noticed the double negative in his post - he's saying that there are no "no-go zones" in the US. In which case, it looks like his argument is "if there were places in the US where the police won't go, like you have in the UK, then I'd bloody well want a gun". Which would make more sense if only he wasn't sadly misinformed about the state of things in the UK.

lol - It does sound crazy when you put it like that. Maybe someone has given him some fake news and he believed it.

Hang on, so you're saying there are actually places in the US where the police will not actually go? And you think the UK is the country that's in danger of a breakdown in civil society? Can you see how bizarre that sounds from a country that doesn't have guns everywhere?

I agree with your analysis on the whole but "no time in the foreseeable future." I think you're wrong here. People like you are the answer, Americans that have enough intelligence to see the ridiculous and self-destructive nature of the current status quo, and the eloquence to explain why; all you've got to do is resist the urge to accept the futility of doing something. I'm not suggesting it'll happen overnight but the cultural shift is happening now and if enough people stand up it may even be the next generation but if it's the one after that or the one after that, surely it's worth the effort? Indeed, a simple ban on automatic weapons would make an immeasurable difference, imagine how many lives could have been saved if he had to manually reload, or even recock?

I don't know that I would necessarily expect two boys (or two girls) to handle the same situation the same way. There is a spectrum of behavior, and it applies within a (traditional) gender, as well as between them.

To a 6 year old:- If one car is going north at 60 mph and another is coming in the opposite direction at 30 mph..... Their speeds relative to each other are 90 mph.... if they crash then they have all the energy from their respective velocities. When you get very, very, very fast... approaching the speed of light, it no longer works that way because nothing can go faster than light... no one knows why..... but I wouldn't worry your 6 year old head about it for now.

I find it very difficult to believe that he said that. A 6-year-old probably does not grasp physical concepts of mass, time, energy, force and 3-D space sufficiently to understand even Newton's laws.

Sports is a bad example. Even amongst people of the same height, weight, age, and years of experience/training there are very big differences. Those with different body types play different sports even within a specific sport body type often determines the position one will play. In an earlier post you mentioned fighting sports and qouted "I've never felt so overpowered in my life"; in both the Boxing and the UFC people have died. Many people are totally overpowered and there has been debates for years as to whether fighting sports in general are ethical. So in bringing gender into that discussion you are merely adding mud to murky water. Even if we shift the sports example to something more mainstream like Football you'd still be dabbling in something which already has ongoing ethical concerns regarding protecting kickers, protecting quarterbacks, concussions, and etc. All contact sports are dangerous. All have seen deaths. All have their own ongoing ethical challanges. Complicating matters even more are Performance Enhancing Drugs (PEDs). Amongst the most elite athletes in every sport a healthy percentage are caught cheating.

Upon review, I agree, but can no longer edit that post.

Whatever his reasons were for doing it - it is another advert to sort your outdated gun laws out. Whatever his reason, Islamic terrorist, white supremacist, mentally handicapped, disgruntled asshole.... if it happened anywhere else we would be saying 'how did he get all those weapons? - this is terrible' - as I is it is just another day in the life for the USA and their outdated gun laws. (I was going to say retarded gun laws but the mods frown on the use of the word - but I feel that it is apt here by definition of the word - the laws are so far out of date and behind the rest of the civilised world that I can think of no better word than retarded - meaning backward, held back, out of date and behind with the times.)

Well, no I do tell you that the speed of light has been tested or else CERN or Fermilab Particles would go faster than the speed of light with around a TeV of Energy. Photons have no rest mass, they only have Energy, but not mass. I know it sounds paradoxical, but it is a true statement.

Speaking as an outsider from a country with Gun control laws, I observe the fact that Americans in general, and particularly their government/congress, lack the intestinal fortitude to stand up to the NRA. This mob rightly or wrongly remind me of that hateful orginization called the Klu Klux Klan. My commiserations to all in your country that have unnecessarily and needlessly lost loved ones.

If the shooter was brown, Trump would scream terror from the rooftops and his minions would parrot it loudly and angrily. I don't need a ton of bricks to fall on my head to know that his deliberate avoidance of the word terrorist was to score points with the NRA and the meager remaining 30% of his base, yet the problem is laid at my feet? Pfft. He's supposed to be a president. When will he start behaving like one? It's not about political points, it's about the truth. Do you deny my point about the hair trigger terrorist epithets he hurls at other groups? Patton Oswald? WTF does that have to do with price of tea in China, or is that just a cheap shot? As to the tragedy, we are in agreement. If Trump doesn't wake up, then how do you expect the rest of the country to do so?

The Las Vegas shooting demolishes the NRA’s “good guy with a gun” argument. It was absurd then, yet how can this statement have any credibility moving forward? Apparently the NRA never heard of positions of advantage as we saw in Las Vegas. Can you imagine the pandemonium if everyone was armed with handguns attempted to shoot back? Clearly everyone else in the hotel would have been at a greater risk. According to Donald Trump, a minority person conspiring to murder people is a branded a terrorist for plotting an attack, even if they never carried it out. He openly advocated bombing their otherwise innocent families. Yet a white citizen with ammonium nitrate in his car and multiple cases of modified or illegal automatic weapons shooting nearly six hundred people at random in a public setting isn't a terrorist? If that's not a classic example of white privilege, then what is it? Agreed, but motive is beside the point. It wasn't an accident. His objective was to scare, injure and murder. Has the attack and responses to Sandy Hook made mass shootings mainstream?

What is this thread about ? A bunch of guys bitchin' and whining like the women in the video ? Yes, men and women are different ( duuh ). Both have various degrees of strengths and weaknesses ( evolution helped with that ). The only problem is when one sex is considered better than the other

If I can pull up some references from other discussions where Republicans were called retarded can you give them warnings too?

! Moderator Note A few things. Firstly, your use of language - specifically your use of the word retarded - needs to change. Secondly, the rules of this forum specifically prohibit members from slurring an entire group of people as you have done. If you can't contribute anything intelligent (or additive at the very least) to the discussion, I would ask that you don't bother contributing.

The trick is to get something cooler than the dew point of the surrounding air so that moisture in the air condenses on the surface in a manner that it can then be collected. MigL's suggestion does all that (it can be as simple as a piece of plastic stretched between, say, four rocks weighted down by four more with a small pebble sitting in the middle to get a bit of slope, and a cup underneath the lowest point to catch the accumulating water.

A sheet of plastic film, horizontally sloped, a few feet off the ground, will cool down much faster at night than the ground. Warmer, moisture bearing, air next to the ground will rise, water will condense on the cool plastic, nd run down the slope into a container. This should give you some water for the next day, although I've never done this; Only seen it in movies/TV.

The title asks when; honest answer is no time in the foreseeable future. While adoration for guns alone isn't a good excuse it is the one tens of millions ardently feel/use. There is no good reason for believing man has only existed for 10,000 years or that there was a global flood yet people have faith in that stuff anyway. Ultimately passion defies reason. People have accepted amongst themselves in a tribal manner that the their heritage and the very notion of liberty itself is fundamentally associated with unrestricted access to guns. I makes no f#$&'in sense to me but is the case none the less.

Anybody who denies that there are differences must be clinically insane. Anybody making value judgments based on those differences must be sexist.

There is no single answer, different neutrinos, from different reactions which are creating them, have various kinetic energies. f.e. the most basic fusion reaction is: [math]p^+ + p^+ \rightarrow D^+ + e^+ + v_e + 0.42 MeV[/math] This equation can be written in longer form pp->He-2->D [math]^2_2 He \rightarrow D^+ + e^+ + v_e + 0.647447 MeV[/math] The more kinetic energy takes positron, the less is left for neutrino, and vice versa. So average energy emitted to environment around star is 0.21 MeV (or 0.324 MeV) or so, per fusion reaction. There is emitted 65 billions per cm^2 area at 150 mln km distance from the Sun to the Earth (inverse-square equation, if neutrinos are emitted uniformly in the all directions). 65*10^9 * 324000 eV * 1.602176565*10^-19 J/eV = 0.0033741838 J/cm^2 = 33.74 J/m^2 (divide by time=1s to have power in watts = 33.74 W/m^2.. Regular Sun photons have 1370 W/m^2 for comparison). Not so much, even if they would be the all captured by the Earth' materials.. This reaction won't trigger Chlorine-37 based neutrino detector. It requires at least 814 keV.

Since no one else want to answer this here goes. When the piston initially starts to move it will generate a pressure pulse immediately in front of it. This pulse will move away from the piston at the speed of sound in the gas and eventually expel a pulse of air at the open end. If the piston continues to move smoothly and evenly it will generate a succession of such pulses which will coalesce into a region of increased pressure air between the travelling initial pulse and the piston face. So once the air has commenced exiting the open end the pressure between the piston and the open end will be increased all the way but will not rise further. Waves or pulses will only be generated if the piston moves jerkily. Edit As a matter of interest you cannot apply Bernoulli's theorem directly here as there is an energy input to the fluid. The setup is effectively the inside of a pump.

Depends on the definition of "arbitrary" I suppose. Day and year are arbitrary in the sense of not having any universal meaning (unlike, say, Planck units). But are not arbitrary in that they are based on obvious things going on in the world around us. But they could also be considered arbitrary because they don't have constant values. Of course, subdivisions of the day, such as hours and seconds (and the number of hyperfine transitions of a caesium atom) are arbitrary in both senses.

I would say the direct connection is momentum. The forces are equal (an opposite) and the time of interaction is the same, so the impulse on each is the same magnitude.

After all that incoherent gibberish, this question. Nothing causes it. It seems to be a fundamental aspect of reality. But maybe it is related to energy conservation, which is related to symmetry; basically the fact that the laws of physics do not change over time.

In modern culture, the only thing the term "race" distinguishes is a vague grouping of the color of the skin. It has no real benefits, even as a social construct, imo.

I think you will find that the French would have used their language, rather than ours. Your claim is just silly. Thank you for clarifying that you have no interest in the truth. You have said that because of teh no-go zones in teh UK we will regret our lack of privately owned guns. But you also say you don't know anything about those zones and can't provide evidence for them. It may be just me who thinks this, but if that's how helpful you are going to be, why don't you just leave?

Most likely because I'm incoherent as well. 1. Evidently, I missed those trials and tribulations. 2. I can't agree with that more. 3. Unlikely, because most of the times you're seeing a therapist for something other than life and death. Or, you can just change your gender.

You can reject what you damn well feel like...It doesn't make your claims anymore valid. In time as is the case with all you lot trying to rewrite 21st century cosmology, or as per the many evangelistic crusades others like to implement, all will be lost in cyber space and mean nothing. Take it easy, OK?

Leave it to you to make this about white privilege. Did he terrorize those people, as well as injuring and killing a large number of them, and making the rest of us afraid of attending public events ? He certainly did. So he is a terrorist ! And since when have you ( or anyone else ) cared about what D Trump says anymore ? This shouldn't be about scoring cheap political points ( should I call you Patton Oswalt ? ) It is a tragedy, and the American government has to wake up and do something about their gun laws.

There are two types of people mainly . White people and black people . lol White people has some advantage over black people . White people are more attractive than black people Why is this such a complex thing to understand .

Oh, boy, my first warning. I just want to point out, it's very much allowed to make slurs against conservatives here. I've seen it done by mods (not naming names). I've seen those insulting posts by mods be upvoted. I've seen Trump supporters be equated to idiots, dimwits, assholes etc. I have personally not seen any action against that. While I steer clear of those discussions, I would encourage you and the rest of the mods/admins to treat both sides equally. I see Raider got downvoted for simply pointing out the double standards, which proves my point. So, slurs and hate speech are allowed, as long they are against the same group of people the mods hate.

I'm well aware of places where one doesn't go day or night in the USA. A no go zone is a place where police, fireman and emergency people don't go. Do you know the difference? If the same happens here in the USA--there are no "no-go zones" in the USA--that is when we all here get out our personal guns--if we have them, I do not possess any--and take back the country. Please see my reply to "DrP" above. Thanks.

Now you know! Further, I reject out of hand any references to the Wiki-pee-D-uh sources. I like my arse, if that's any of your business. (Schwing! top of the page!)

Talking about entangled particles,,let say 2 superposed photons on the z axis one at the base and the other at the top and they both have information the distance of separation on the z axis is (zero time) infinite and constant..so to send out information on the x or y axis perpendicular to the data from the z axis any where along the z axis is the worm hole that make it possible

Which do you mean? Or do you mean the Second Amendment of the US Constitution? I can tell you that you might wish you had a firearm very soon in Britain, depending upon where you sit, in the not-so-distance future. I have written off your nation, it has been going on....I think, 4 years now. I'm referring to your level of Sharia compliance. Do you know what I mean? This brings up the timely question: When will you be requiring the U.S. of A. to rescue either you Europeans or you British in particular when the conflagration, aka breakdown in civil society begins? I need to plan my future. In many of the European countries the deterioration is at a critical stage. In other words, the state of our gun laws is a preposterous subject in comparison to your breakdown of civil society. I will use three words: No Go Zones.
