The Red Scare of the 1940's-1950's | I think the biggest point Arthur Miller was trying to make is that the Red Scare resulted in people being branded as Communists with little or no evidence to back it up, much like the Salem Witch Trials admitted shaky "spectral" evidence to convict innocent people. Both situations were also an opportunity for people to... |
How could water be potentially extracted from atomic energy? | What you're most likely thinking of is *desalination*, which involves extracting fresh drinking water from sea water.

Using an energy source like nuclear or solar can achiev... |
Why do mobile / cell phones make that buzzing sound when close to speakers? | The signal your cellphone is sending out is a form of electro magnetic radiation.

Why would Apple agree to allow Siri to feature in Microsoft 'Cortana' advertising? | They don't need permission to just feature them in advertisements if the advertisements are fair and not misleading.

How do colors appear on calculator screen when pressing them? | I don't know the process, but it almost certainly has to do with the polarizing effect of the liquid crystal.

What is the difference between a BA in a science and a B.S. in a science? | This is 100% dependent on the whims of a given school, and there is no general answer to it. In my experience, if both are offered in a natural science, the BA takes a bit more superficial look at the subject, and may avoid research methods, labs, etc. The credit hours required *may* be less. For something like psychol... |

The second we developed the nuke it became impossible for them t... |

How do big names get their usernames on social networks? | There are laws against cybersquatting, which means you go buy up all the celebrity domain names in the hopes of either pretending to be them or holding it for ransom.

what is causing the sea level to rise? | It's really two factors. A lot of ice isn't floating in the ocean, it is sitting on land. Antarctica is a rocky continent largely covered in glaciers.

Why is power-cycling such an effective solution for most common problems with electronics? | Suppose you are in a very complex maze, but you have a detailed list of instructions: Go forward, take the third right, then a left . etc. Now, suppose you make a mistake.

How is music so accurately translated on to vinyl with just lines? | Music causes vibrations in the air, which are caught by your eardrum when you hear music.

The mold is then used to press viny... |
How can the universe be infinitely big? | I’d like to say that no one really knows what lies outside our universe. It can’t really be anything can it?

Why is it that despite how much CGI has improved in the last 20 years it is always possible to tell when human faces are digitally rendered? | The term is “uncanny valley.” And yes it is much harder to make something real look realistic.

We're so good at it our b... |
What really happens in an addicts mind when they decide to give something up to continue using? | I gave up music to continue using percosets.

Why do some cars have the RPM meter as multiples of 10 (which have to be multiplied by 100) when others have x1000, which is a lot better? | It's usually just a design choice.

Why is the 1982 film Blade Runner considered a legendary and coveted masterpiece? | Well for one, scifi-noir was a rather inventive hybrid, & it is so well done on both fronts.

How does NVIDIA manages to bring driver updates to such a large and old lineup of GPUs ? | It's their core business to do this. If they would only support the latest video cards the customers would get very upset and all move to other brands. Also, the nvidia cards all have a fairly similar architecture.

Why do I find myself 'falling in love' as soon as any woman shows me attention? | **ELI21**: Essentially there is a strong release of neurotransmitter chemicals when you first meet someone.

Why something purchased via mail order took 6-8 weeks to deliver instead of the few days it would take today? | A huge factor is that it took everyone 6-8 weeks, so consumers expected it to take 6-8 weeks, so there was no huge incentive to improve.

How do the glasses in this video allow a blind person to see? | It would only work for somebody who is legally blind, not totally blind.

Tyre tread I understand gives grip/traction, whats the point in racing slicks or F1 style tread-less tyres? | Grip is proportional to the surface area of contact - therefore the more contact surface you can have between the tire and the road, the more grip you will have.

Why do most train stations have no barrier between the platform and train? Isn't this a massive liability? | There's also no barrier between the vast majority of roads and sidewalks, just a little strip of something that's a different color.

Difference between AFC and NFC? | As far as I know, there is no functional difference between the two. It is just two halves of a league.
