You can trademark a specific way the name is written so a guy named McDonald can open a burger shop with his own name but he probably can't use big Golden Arches and a clown dresses in red and yellow. Generally the rule is you can't confuse or try to trick the public into thi... |
Why is artificial light used to grow plants on ISS instead of the sun? | If you leave the window shades up all the time, you will heat the inside of the ship up a lot.

Why do humans feel the need to take care of small/vulnerable/"cute" animals? | We're biologically tuned to love creatures with certain characteristics - big eyes, pudgy round faces and limbs, tiny mouths, etc. - because that's the way our young need to be designed for functional reasons.

What would happen to all the actively cooled nuclear waste if civilization collapsed? | Depends on the design of the system, but most will detect lack of people watching and auto-scram.

Why do we translate people's names? | At the time Latin was still the international language of the educated and Christopher Columbus is the Latin version.

As an example, Jes... |
What is the U.S government doing to reduce the nations debt and how serious is the debt problem? | Well, it's very important to understand one thing before we start. There are two problems.

Why can carrion-eaters consume decaying flesh, but humans risk illness from raw meat? | Everything risks illness from contaminated meat. Raw meat in and of itself does not pose a threat.

Why does the U.S. Navy have fighter jets? | The pilots who fly in the Air Force are trained to take off and land on land.

why is gravity/relativity shown as 2 dimensional? | Because we can't see in 4 dimensions. Space-time is visualized by cutting 3 dimensions to 2 dimensions and then showing the change in gravity/relativity in the 3rd dimension. The 3rd dimension represents the 4th. Also, things in a solar system are lined up in a disk! so the 2 dimension representation is really accurate... |
If you jumped out of a building/plane/something high with a chair under you, and jumped off at the last second, would you stop falling as fast? | Your terminal velocity is about 120 mph . So to counter this, you would need to somehow be able to jump in such a manner to accelerate to 120 mph in the opposite direction.

Why are some pimples really painful, and others are not? | What I've always heard is that it's related to how deep the infection is. So, a pimple with sebum down to the second layer will hurt more than a pimple that is only present in the first. Something along those lines. |
Why do my cats and dog tolerate loud noises all day, but cower at even distant thunder? | It is not the sound alone that scares animals, it is the combination of the sound with smells and pressure changes.

What does this sentence means: a car was using a camera processing an image of 320 by 240 pixels at a range of only 100 meters. | Um, the description seems to be both descriptive and confusing at the same time. The camera's own resolution is 320x240 pixels. By this I mean when you take a picture with that camera and transfer it out, the image is only 320x240 pixels wide and tall respectively. The camera will process information at this resolution... |

Why are some foods canned and others jarred? | A few things to consider. Cans are cheaper than jars, and jars are resealable and can be stored in the fridge for weeks without any negative side effects.

Why do companies with a large amount of cash still issue debt? | Taking on debt spreads financial risk across a longer period of time. If I shell out 100% today, I'm out 100% today, and 100% tomorrow of my investment goes south. I'm screwed the day after tomorrow. If I shell out 2% today, I'm out 2% today and 2% for the next 4 years, so if things don't work out, I can continue to op... |
Why is "supply side problem" of hiring women in tech invalid? | You should ask those people why they think the argument is invalid because with what you 've posted here, I can't see why it's valid.

Why did fully wireless earphones/earbuds take so long to reach the market, when those quirky bluetooth headsets have been around for so long? | A big part of the problem was and still is that the buds need to receive a stereo signal at exactly the same time.

It would use massive amounts of power consump... |

cars are at 12V on the frame relative to the ground. should we get shocked when we touch it? | Nope, as it's not connected to the ground, it's free-floating.
