Is it possible to have a dream that would permanently traumatize you?

There are certain things and events that can affect and damage our brain by giving us phobias, traumas and mental problems. Is it possible that dreams can cause our brain harm?

How would an ordinary ~$20 knife from a sporting good store compare to a knife from say the 1300 A.D. in terms of quality, workmanship, and how well it could hold an edge?

Why isn't acuity constant for the entire eye?

Posted: 24 Oct 2016 08:46 PM PDT

Why don't we have fovea-level retinal cell density throughout the eye; why is central vision limited to such a small region?

Can animal toxin (i.e. Poison or venom) affect plants?

I saw a post today about a Venus flytrap capturing a wasp. If the wasp stung the plant would it affect it?

What in our brains causes feelings of hopelessness associated with suicide?

Posted: 24 Oct 2016 08:33 PM PDT

What about depression causes people to have the "hopeless" feeling that pushes so many people to suicide? Why don't we feel this while we're happy and why would our own brains be so easily led to killing itself despite the common belief while happy that suicide doesn't make sense?

How do we know quantum mechanics is actually random?

Posted: 24 Oct 2016 08:00 PM PDT

Why is this the the belief in quantum mechanics? Why wouldn't something like the spin of an electron be determined by some hidden variables? This seems like a cop out, as if they're just saying "we can't predict it's impossible to do it". I'm sure I'm wrong though, what am I missing?

How do Human bodies detect humidity?

How exactly is it done, and which body parts play a role in doing it?

What is the commonest cause of death in common laboratory mice?

Posted: 24 Oct 2016 02:03 PM PDT

I'm primarily interested in the commonest cause of death in mice in life-long studies in which mice are left to live out their lives without major interventions. For example, common lab mice, say a C57BL/6 strain, are placed on a normal diet and monitored until they die, what is the most likely cause of death? I think neoplasia may be the most common cause of mortality, but I'm having trouble finding sources clarifying the details. Can anyone help?

How can both nuclear fission and fusion release more energy than it takes to get them started?

Posted: 24 Oct 2016 04:31 PM PDT

From my very uninformed perspective, it seems contradictory that breaking things apart (fission) and forcing things together (fusion) would both release more energy than it takes to cause them in the first place. In other words, my intuition would be that one of them might release energy, but the other would consume it.

Can a pure substance have more then one triple point?

Posted: 24 Oct 2016 09:45 AM PDT

I am aware that a triple point is a point on a phase diagram at which three phases of a substance co-exist. Is is possible for one pure substance to have more then once triple point?

How do photons, frequencies, and quanta work?

Posted: 24 Oct 2016 10:56 PM PDT

How is light able to knock off electrons from metals without changing the metal in the photoelectric effect?

What does the equation E=hv by Planck mean and how was it found?

Where does Planck's constant come from?

How can the amount of energy of a particular photon depend on the frequency of the radiation if they carry only one quantum of energy?

Thank you!

How do you solve the puzzle?... "Let's say we have 10 quarts of milk and replace 4 quarts with cola, then stir it till its homogeneous. If it is repeated with the blend, how many times will it take to have 10% milk and 90% cola?"

How do you solve the puzzle?... "Let's say we have 10 quarts of milk and replace 4 quarts with cola, then stir it till its homogeneous. If it is repeated with the blend, how many times will it take to have 10% milk and 90% cola?"

For example, the first replacement results in 60% m 40% c. The second replacement removing 4 quarts of the 60% m 40% c blended 10 quarts and replacing with 4 quarts c results in what new % m % c ?

How are results changed?... because of https://www.youtube.com/watch?v=aKPoQYevoLs

Are humans born with innate fears or are those fears originated from some specific event in life?

Posted: 24 Oct 2016 08:15 AM PDT

For example, if a man has arachnophobia, has he always been scared of spiders or did he have a bad encounter as a child that gave him that fear for the rest of his life?

Is it possible for viruses to fight each other?

E.g. A person carrier of both HIV and Hepatitis B virus.

After watching the recent Black Mirror episode "Nosedive" and comparing it to my own experience with services like Uber, I am wondering what does science say about 5-star rating systems, and what alternatives might work better?
