Do infants that rely on sign language communicate as poorly as infants that use their voice or are they well spoken due to a more 'tangible' language?
I forget what age, she was probably 2, but my niece learned a few words in sign language and it helped communicate her needs, such as thirsty, hungry, and so forth. All around the time she learned to to talk. So her parents would make the sign and say "thirsty" so she learned to say it but sign it as well so there was ...
because there is a 1 million dollar reward for anyone who comes forward with proof there is an afterlife, how come the long island medium has not come forward? or any other medium?
Presumably because they aren't capable of providing verifiable proof.I'm unaware of any such reward . The Randi prize is more geared towards demonstrating paranormal powers, but I suppose a "proof" of the afterlife could qualify. However, I'm a little unclear on how, exactly, one COULD prove it, especially to the satis...

A whitening toothpaste advertises 1 shade whiter every week. Theoretically, could I brush my teeth 28 times in one sitting and have my teeth 2 shades whiter after?
No. Brushing has nothing to do with it, the effect comes from having the chemicals sit on your teeth for a weekNo. You could have your enamel removed by overbrushing and have a lot of dental work incoming thoughFrom what my dentist tells me, "whitening" toothpastes just feature more/grittier abrasives. Probably not a g...

When selling a car on craigslist why do people call, sound excited about the car, say they are coming over right away to look at it and then never show up?
> Did they forget? Are they pathological liars? Do people on craigslist just have a different definition of "right now"? People are fickle. They routinely make promises and then don't follow through. I 've seen this with recruiting volunteers for a charity thing, scheduling appointments for private tutoring sessions, s...

How video game hosting works.
What do you mean by "hosting"? There are many topics that we could go into. Do you mean "servers"?

When it's cold, your nose gets cold but your lungs, and the air coming out of them, is still ~98f/37c and the air has picked up a lot of moisture from your lungs. When it contacts the cooler tissues of your nose, it condenses and eventually drip...

Why do some people you see have money but do not seem like hard workers, while others who do seem like hard workers live in poverty?
The metaphor "The Rich get Richer and the Poor get Poorer" is quite true. I'm sorry to be the one to break the news to you, but money makes money. People that are successful probably had money to get them to the point where they're aloud to be lazy. It seems like thats how society works nowadays. :s
Why did so many Caribbean nations have serious discussions about joining Canada?

Why is is that people who don't make much money always have so many kids?
Remember that in America at least, there are huge tax incentives to have kids. I work at a credit union, and it's not uncommon to see $5,000+ tax returns. I've seen two for around $8,000. I have a relative that has kids for the child support and tax refunds that they provide. She doesn't worry about how much the kids w...
Some Soap/Shampoo rinses off with water quickly, while some others leave a slippery residue even after rinsing off for a long time. I hate this. What is the substance that is doing this?

Why can radio waves go through walls, while microwave waves can't, and light can go through some materials?
For the same reason you can have an object that's transparent to blue light and not to red. Different wavelengths of light interact with different materials. You're probably thinking of materials as "solid", so that the light "hits" the atoms in it, but that's really not true. Even a "solid" object is almost entirely e...

If my company can decrypt my HTTPS traffic?

Why is the Nanking massacre so controversial among the Chinese and Japanese? Which is correct?
Unlike Germany, which took the high road of apologizing for all of their wartime behavior, the Japanese have never fully taken responsibility for their war crimes. Comfort women are the other well-established atrocity that comes to mind. To be fair, Iris Chang's The Rape of Nanking presents itself as a scholarly book b...
Why do most Americans ignore the speed limit on the highway?
California was probably a poor representation of how *most Americans* drive. They are notoriously fast. Maybe it's because they're wound up from sitting in traffic. In terms of traffic enforcement, it is well-known that most law enforcement is unlikely to stop for 5 or 10mph over on a highway. Although you could be pul...
What about orgasm that makes it feel so good that we want it more and more?
/u/casey_pritam has it right, but to go more in depth: The act of sex itself is exercise, and so you're already going to get what amounts to "runner's high" afterwards.

Why do people no longer smoke opium as much as they did 100 years ago?
In short: because opium has been distilled into more potent forms. The long answer is the history of opiates, from which opium is a relative.

The mining strikes in Northern England in the 80s and why Margaret Thatcher was hated for it
Margret Thatcher came into power in a similar fashion to David Cameron, i.e. the country was spending way too much money and she had to reduce this deficit.

If the Toba supervolcano nearly killed off human species,why not larger species such as elephants,bears et cetera
The evidence for the Toba theory is very controversial. Presuming it as the basis of your question is problematic. That said, humans are not as sturdy as bears or elephants.

Why are we able to put our hands through liquids but not solids?
Liquids can be very complicated but are still liquids. The molecules in liquids are fairly short and do not bond much with each other. I am putting in these qualifiers.

What does "integrated" or "dedicated" or "onboard" mean in reference to graphics cards?
Integrated graphics cards use your computer's RAM and processing power and aren't very good for running 3D programs.

How gas masks work and their effectiveness.
The round thing on the front is a filter. If you have a Brita water filter at home, you know how a filter works; stuff comes in, bad stuff stays in the filter, and purified stuff goes through. The gas mask does the same thing, except to air, and filters more compounds than a Brita does.

No vaccine works perfectly for everyone. Some people don't develop a strong immune response for one reason or another. This is one of the reasons it's important to vaccinate everyone. When enough people are protected, it's harder for a virus to spread to the people who aren't protected.
Why do you need a NASA lens to record candle lit scenes on film, yet the human eye is as small as a mobile phone camera and can see low lit scenes just fine?
Our brain is incredibly powerful and can 'compute' the dynamic range and the white balance of everything we see. Even the the most expensive sensors on the best cameras available today can't recreate the wide dynamic range our eyes do for us, at least not without combining multiple images.Example. When driving through ...
How exactly do tinted windows work?
It's basically a film that you put on the window, making it darker inside than outside. You can see through glass-like things easy if the opposite side is better lit. This is how 2-way mirrors work, and why you can see inside lit buildings at night, but not during the day.

So if something raises in price from an initial $0.01 to $10, that's 999 bids, which, at $0.60 each, is $599.40 that the company has made in non-refundable bid...
Why do bombs squads blow up "packages" that they determine to not be a bomb?
Maybe it was for fun. Maybe you can't be too careful. Either way, any time a threat is made, it has to be taken with utmost precaution. Even if a baby doll sounds like ticking is coming from its leg, it's a threat.
Why do professional swimmers wear 2 caps when competing?
So I was actually wondering this out loud the other day while I was watching the Olympics with my wife, and not 10 seconds later the commentator on the TV actually explained it. He said occasionally you will see some swimmers wear their goggles with the strap on the outside of their swimming cap, but most wear them wit...
