Why does half and half in containers not have to be refrigerated? How come it can be left out for days while milk has to always be kept cold?
Are you sure you're not referring to non-dairy creamers? Half and half most certainly needs to refrigerated.
Why proteins are shown in scientific papers as bunch of tangled wires and arrows, and not like some kind of chemical element or something similar?
Proteins are molecules, like water, not elements like hydrogen. But instead of having three atoms connected like water , they can have hundreds. They are structured in ways that look all twisted as we
Why is quantum physics so often mentioned in philosophy and so-called “enlightenment” texts?
One of the main points of overlap between philosophy and quantum physics concerns whether or not there is true randomness-not just events that are beyond our current predictive ability but things that
Why does it feel colder when you get wet?
when water evaporates off your skin, the water takes some energy from its surroundings (meaning you) in order to change from a liquid to a gas. This is also why sweating makes you cooler. The evaporat
Why do we get to decide if Iran is allowed to make nuclear weapons?

Why does hot water (or heat generally) clean better than cold water (or cold generally)?
It's all about the chemistry. Heat is a measure of kinetic energy, so hotter chemicals are moving faster. In most chemical reactions adding heat will speed things up as the faster moving molecules wil
Why were the the bodies of those who died of a fatal dose of radiation at the Chernobyl disaster still considered toxic and buried in Zinc lined coffins?
Two things. First, they probably got radioactive material from the accident site all over themselves. It's not just radiation that's escaping, it's also actual physical radioactive material that can c
Why do we get cold chills when we’re sick?
Your body is pushing its limits (from cold to hot, repeat) because it's even more annoying for the virus in your body than it is for you as a person. You merely feel cold or hot, while the virus can't
Why are the connections for the vent in a clothes dryer so frustrating and seemingly inefficient?
You are tackling this as a novice. The experienced people have done it scores of times and it is much easier for them. But I agree with you.
Why electric cars are not regular thing?
Range anxiety. The typical gasoline-powered vehicle has a range of about 300 miles, and can be refueled in mere minutes. The typical electric vehicle that is affordable by most consumers (i.e.
