Do you think there is something wrong with society which pressures women to study for many years and then work before having to give it all up to give birth and raise children only to find it harder to re-enter the professional workforce later in life?
John Cuthber replied to mad_scientist's topic in Ethics
This seems a rather odd comment to make on a site that, in principle, provides the opportunity to post and learn knowledge, but without any reward. -
So, how long would it take the monkey to type out Hamlet?
John Cuthber replied to Lord Antares's topic in Mathematics
When I was a kid we were taught to program computers. Some of the stuff we did was not on the syllabus. It didn't take us long to work out that you could get a computer to assemble random four letter words and print them on the screen. We were, of course, delighted when it came up with rude words. The monkeys, given time, would randomly type Hamlet in the same way that the computer typed "fork". -
Knowing how dumb people are, they would probably start a religion.

Distinguishing between HSS and Tungsten Carbide
John Cuthber replied to StringJunky's topic in Engineering
WC isn't magnetic. I'm fairly sure HSS is. -
Fructose's fat (overweight causes). Starches too
John Cuthber replied to Capiert's topic in The Lounge
The body is generally quite good at converting chemicals. Starch, for example, is quite rapidly degraded in the stomach to form glucose which is then absorbed. About a quarter or a half of the fructose is converted to glucose- the rest is metabolised via different pathways. What is in beer that makes people fat is, essentially, calories. It doesn't matter much if those calories are in the form of sugar or alcohol; if you eat more energy than you use, the body stores the excess by making fat. Incidentally, a linguistic point; when talking about people in English, fat is not the same as thick. Fat means they weigh too much. Thick is usually taken to mean "thick headed" i.e. stupid. So, yes, beer makes people thick- but not in the way you meant. -
Fructose's fat (overweight causes). Starches too
John Cuthber replied to Capiert's topic in The Lounge
You have the wrong idea. -
It may be your worldview, but it's not actually correct.

Good point- at physiological pH it might also be bicarbonate/ carbonate rather than a "free" proton.

finding the equation of a line ( continues data)
John Cuthber replied to steve crr's topic in Analysis and Calculus
A quick look suggests that there's something else strongly affecting some of the data. If you remove the first two rows of data the remainder fit very well to a linear model. Given how much easier it is to work with linear approximations than with anything else, I'd go with that. Was there anything special about the first two point? Are you able to monitor the temperature of the battery? -
Hydrogen ions in any solvent at all will stick to a molecule (or several molecules) of that solvent. It's typically something like H9O4+ As part of the process of being pumped, a proton might temporarily be stuck to a protein.

finding the equation of a line ( continues data)
John Cuthber replied to steve crr's topic in Analysis and Calculus
First question: are you using Excel? (I'm not sure how it works with other stuff). Second question. Can you get it to plot a scatter plot of miles vs charge (or whatever)? If so, it should be a matter of Right clicking on the graph and selecting "add trend line" then selecting the type of trend line you want (polynomial or whatever adn clicking the buttons for "display equation on graph" (or something like that.) Failing that, I'm curious to know what the data looks like. If you post it here I will stuff it into a spreadsheet for you (as long as there's not huge amounts of it). -
Yes, you can. (neodymium glass is famous for it) But it's unlikely that they do. Those glasses are worse than useless for two reasons. They could fool people into thinking they were "safe" and also, because they will attenuate visible light, the pupil of the eye will open up to compensate making it more likely that you will get the beam in your eye.

John Cuthber replied to steve crr's topic in Analysis and Calculus
You can fit other curves. -
finding the equation of a line ( continues data)
John Cuthber replied to steve crr's topic in Analysis and Calculus
You can use a spreadsheet (excel , or the open Office versions should work) to fit data to a model. It will also plot graphs which is handy. -
Is it Friday yet?

Perhaps, but he's not the one spreading that abuse of Penrose's work here It's not sound anyway- as has been pointed out. Anyway, if he's not clever,. he's not worth citing. If he is clever then we can assume he understands the conclusions from his own work; and he's an atheist. If you think he's mistaken then you need to show what mistake he made.

What can be done with this Hawaii volcano?
John Cuthber replied to Awkward_Pause's topic in Science News
Walk away, and think twice about coming back when it has stopped. -
Be careful what you wish for. As far as I know, the only immortal human cell lines are cancers.

Is MS primarily caused by the jaw and cranial bones?
John Cuthber replied to NothingNobody's topic in Medical Science
Or causation, but in the other direction. Maybe MS causes jaw problems. -
When we were babies we were in the position of the person trying to decode a language that was unknown to him and with which he had no previous link. We did OK. Why wouldn't he?

Trump to recognise Jerusalem as Israel's capital.
John Cuthber replied to StringJunky's topic in Politics
I think most people would become terrorists if pushed hard enough. Trump just announced his intention to push harder. I suspect the outcome will not be good for humanity. -
Are you going to get upset when someone points out that any religious belief that stems from reason isn't religious (I'm a staunch atheist, but I will believe the same thing if you show me that it's based in rational thought) so the only things that are based on religious faith are not rational?
