How do these MLM companies (Nerium, Rodan+Fields, etc) afford to buy their executive sales people brand new vehicles free and clear? What's the catch? | You are correct, there is a catch. The vehicles are not free and clear, not by a longshot.

How could two different species, Neanderthals and Homo Sapiens evolve out of only one single species, the Homo Heidelbergensis ? | Two sub populations diverged over time until they couldn't interbreed any longer.

The idea of a parallel universe moving backwards in time | The laws of physics work just as well going backwards through time as forwards. But time clearly goes in one direction, so we have to figure out why that is. The explanation offered by the physicists quoted in that article is that time points away from the Big Bang. So if you drew a timeline of the whole universe, you'... |
Why does uncertainty feel so much worse than rejection? | Humans like to categorize things and plan things. Not all of us are great at planning, but we all do it.

How can a small AA battery have always the same voltage (1.5V) but not the same lifespan (no-name VS major brands)? | The voltage is dictated by the chemistry of the battery. Any alkaline cell will have a voltage of 1.5V; if you buy an alkaline battery with a higher voltage than that, it's because there are [several alkaline cells connected in series]. An alkaline cell derives its energy through the reaction between zinc and maganese ... |
Why do some film sets only cover a part of the whole visible frame with a blue/greenscreen? How does this help at all if it isn't actually behind the whole scene? | The blue screen only needs to cover the transition from a character or part of the scenery which is to be cut out.

How are we able to change pitch while whistling? | The size of the opening and force of air is what determines the pitch. Moving your tongue back and forth can change pitch .

How do AVG make my computer boot faster? | Speed up programs don't do anything.

Why does WiFi range seem to be determined solely by the router/AP? | The stronger transmitter also has a more sensitive receiver.

From our limited understanding our memories are formed around it's ability to form paths of neur... |
How does a pitcher plant remove the contents it cannot digest? | The pitches are just leaves so yeah, they just shed them eventually and it's not really an issue.

How are criminal sketch artists so relatively accurate just based on witness accounts? | They're not, actually. Fact is, they are a terrible way to get an idea of what someone looks like and rarely have any accuracy at all. The flaw is two-fold.

Hetergenous mixtures - this is like mixing legos with duplos and wood blocks. Th... |

How are the calorie counts in foods determined?

When you take a pill, how does it know "where to go"? | It doesn't. The medication is absorbed into your bloodstream, and goes everywhere in your entire body.

Why are/were women considered inferior to some degree in so many cultures in human history? | I'm not an authority on this by any means, but I'd say it has to do with men being physically superior to women.

No one can say you aren't th... |

Is infinity a possible thing outside of theoretical ideas? like physically? | When we get infinity as the answer to a problem in physics, we consider that to mean that the math we were using was wrong.
