I was at Politicon, and there was this booth that was presenting a border wall solution. A force field, and they called it parabolic laser? I googled their company name Conorizon and I can't find anything. I also tried their little experiment and it failed. Any insight?

Is this room more than 3 dimensional?

Posted: 01 Aug 2017 03:52 AM PDT

I watched this video here. I think this room has more than 3 dimensions, because its deforming the whole time, it has an extra property.

Isnt the deformation of the room a dimension on its own

Is it even possible to picture a 4 dimensional room? And is yes, can someone link it to me please?

What purpose does chilling the instruments of a telescope serve?

Posted: 01 Aug 2017 03:09 AM PDT

Let me preface this with I have no formal education in advanced physics or engineering or astronomy or anything relative to this question/questions. My background is in biology focusing on zoology, so please forgive me if I use incorrect terminology in relation to measurements or any other lingual blunders I may commit. OK, so I know I'm way behind on this one, but I've only just started looking into it. My question is about the Lucifer Telescope. Why is it necessary to chill the instruments to about -351 ℉ (I'm American and this unit of measurement for temperature is what's most comfortable for me in terms of comprehension. I'm sorry) to make near infrared observations? What is the relationship between the temperature of the instrument, the temperature of the galaxy/universe (I guess -455℉), and the ability to observe near infrared wavelengths? Is the telescope used to search within different wavelengths? Or is none of this even a thing and they're just chilled because it is a very high powered telescope requiring a lot of cooling? Again, I apologize if these questions are gibberish, just trying to find the right way to word this with such limited knowledge of proper terminology to convey what I'm asking has been exceedingly difficult. Thank you.

What conclusion can be drawn from statistically insignificant results? (Layman question and text provided)

Posted: 01 Aug 2017 04:43 AM PDT

Hello guys, I just wanted to ask you if somebody could give me very basic (layman) explanation about one question. If for example you did an experiment on yourself where you tried a drug to see if it helps you with your condition, you took it 100.000 times but it only helped you 3 times. What conclusion can you draw from this? Is the result statistically not significant and therefore the hypothesis that a drug helps you can be rejected (so you can conclude that this drug doesn't help you). I know this is a very lame example, but try to give me an explanation for this particular scenario. It seems logical for me to conclude that a drug doesn't help, but I want to see it backed up by science. Thanks in advance!

Why do different species have different lifespan?

Posted: 31 Jul 2017 09:11 PM PDT

^

For example:

Dogs have an average lifespan of 10-13 years;

Sea Turtles have 80 years lifespan whilst humans have est. 30-50 years lifespan(without medicine). Why are they different?

Is it because different species have evolved differently and our body cells are 'programmed' to die/weaken at a certain point in our life? If so, was/is/would there be a species that would evolved in a certain way to be 'programmed' with a very long/infinite body cells' lifespan?

P.s: sorry if I got some facts wrong or sound ignorant, I have no idea what I am talking about(hence asking this subreddit).

How does one find the activation threshold of a diode?

Posted: 31 Jul 2017 04:45 PM PDT

I've been tinkering with some electrical circuits as inspired by my physics class and while graphing some different kinds of diodes under rising voltage, I noticed the before they come a mostly constant resistance they a sometimes slow, sometimes fast ramp up, looking a lot like an exponentional function. What causes this behaviour, when in theory they should just have 1 activation voltage? If I wanted to find the specific voltage myself, do I simply take the point with the lowest amount of current, or do I compensate for the ramp up somehow? I feel this is tied to my imperfect understanding of what exactly a semiconductor is

Regarding the matter-antimatter imbalance and neutrinos: Did the same (ever-so-slight) imbalance between matter and anti-matter apply to neutrinos as well?

Posted: 31 Jul 2017 06:00 AM PDT

I'm trying to ascertain whether some clue could be garnered if we study neutrinos and anti-neutrinos and the matter-antimatter imbalance in the early universe.

I'm thinking that because neutrinos so rarely interact they would have taken off at straight lines as space-time was being created.

The annihilation process that matter underwent with its antimatter counterparts wouldn't have (or would it?) applied to neutrinos.

Are there any studies that address this possibility, assuming it actually is a correct assumption on my part?

Do earthquakes have a "season"?

I've been living in Northern Japan for over a year now and have noticed that last spring and summer there were MANY small quakes, like several a month, but in the winter and early spring they stopped, now they have started again so it has made me wonder if there is a "season" for earthquakes. (Or if it's just a coincidence since I have only been here for a short period of time.)

Why is a real string pitch depending on the wave amplitude?

Posted: 29 Jul 2017 03:35 PM PDT

When you pick a string on, say, a guitar, with exaggerated force, you may notice a higher pitch, then rapidly decreasing to the expected one when the wave amplitude decreases. This pitch shift is especially noticeable on the lower strings (where larger amplitudes are possible). What is the physical phenomenon leading to this? How can one express this dependence between pitch and amplitude mathematically?

Edit: This is not about higher harmonics. There is a small but perceptible shift of the fundamental towards higher frequencies. My guess is that the deformation applied to the string increases the tension, which in turn increases the wave frequency. Is this a possible explanation?

Does sound travel through spiraled tubing at the same speed as through straight tubing?

Posted: 29 Jul 2017 02:21 PM PDT

A co-worker and I are having a disagreement on this issue.

At our job we use headsets connected to a handheld radio for communication. We wear those CIA looking headsets in our ears. The wire runs to a speaker which is clipped to the back of our collar and then the sound travels through a small tubing, which is straight, spirals in the middle, and then loops over the ear and into the earpiece.

I cut my tubing down from the speaker to the spiral, so it stays somewhat tight in my ear.

While assisting a new employee i cut her tubing down even closer to the spiral in the tubing. Almost to the point where the speaker produced sound straight into the spiral before getting to the earpiece.

Halfway through the shift, he speaker blew out and the sound is crackling.

My co worker said the speaker blew because the sound gets too backed up going through the spiral, compressing it and blowing our the speaker.

My argument is that the tubing is all the same diameter, and the sound is traveling at the same rate whether it is straight or spiraled. Also, why wouldn't the spiral compress it even if it did have a few inches of tubing before the spiral.

I have searched for an answer with no luck which is why I am here. My co worker will need me to have some scientific information or sources in order to concede.

Thank you all.
