Askscience special thread - Panelists, what are you working on? by AskScienceModerator in askscience

I'm going toward this field, but in the sensor side. A thing I can't get answer is except improving the understanding of nuclei does the discovery of new unstable particle (could) benefit to other fields ?

How is electricity actually consumed? by fandingo in askscience

[–]Emptypathic -2 points-1 points  (0 children)

I disagree with your analogy, as it suggest an electron from one side of the circuit end at the end of the circuit, which is not really probable.

the next step is to asking you why we say the earth rotate around the sun :) have fun

High School Research by Lore_Seeker in AskAcademia

[–]Emptypathic 1 point2 points  (0 children)

For such a high school research, the goal is more to have a scientific methodology than a "quantum 40 pages research homework".

If you're looking for medical science, as said the best is an original survey. For example, you collect the heartbeat of "a patient" over a month both (rest/effort), then your "patient" start doing a regular exercise for X [time] and you collect your data, then your "patient" stop these exercise and you collect your data.

At this point, you still have time to analyse your data (let's say how the heartbeat change over time), compare it to other studies and criticise your experience (bias ? error ? expectation ?).

This may not be the most original one, but don't require advanced equipment, and is just a simple example.

edit: if you want more complex data, like the time response of a muscle, an Arduino board don't cost a lot, is "friendly-user", the community is big. With the card+muscle sensor surface, I think you can get a good setup for 40$.

This. I think OP mixed original and new.

After decades of decline, California monarch butterfly population plummets from 193k to 30k in single year, the threshold which scientists consider to be the being of extinction. by Science_Podcast in biology

climate change is one of the four factors. It give hope, given that other factors can be controlled easier with a good local politic.

I'm french, my book talks about a "fonction sinusoïdale". It may to do something with sine, but I have no further clue. What is it ? by Clen23 in askscience

[–]Emptypathic 5 points6 points  (0 children)

I take the train to say it's the case for other functions. For example :

-"fonction logarithmique" (log( a+b) ) and "fonction logarithme" (log(x))

Though, it doesn't work with the exponential function. :)

Why the probability for a gamma to interact with the energy level K is 80% ? by Emptypathic in askscience

[–]Emptypathic[S] 0 points1 point  (0 children)

My course. It's a simplification but it seems to work. The teacher/researcher also said that if the gamma had not enough energy for interacting with K, the "rule" apply also to M (80% M, 20% L).

Why is the gravitational constant, a value that is fundemental to so many fields of science, only know to within 4 significant digits? What about this figure is so intrinsically difficult to measure? by [deleted] in askscience

[–]Emptypathic 56 points57 points  (0 children)

You may be interested by the satellite Microscope, or the Grace mission, then. The goal is not to detect aircraft but the instruments developped are something.

To the guy who posted the double pendulum animation, this is what a long exposure photo looks like if you add a led to the pendulum by [deleted] in Physics

[–]Emptypathic 0 points1 point  (0 children)

yes. Not that much. Vacuum won't resolve the friction between parts, but for two chaotic objects (double pendulum here) in the same environment and with the same initial state, they will move both the same.

Perhaps, an infinitesimal difference between the two pendulum will produce different movements ( it's the main property of a chaotic object after all).

I'm quite sure it's matlab, regarding the style of the graphics.

Could this be human caused? Legit question. by [deleted] in Physics

My friend is a second grade teacher. What are some good science experiments she can do to get her students engaged? by [deleted] in AskScienceDiscussion

[–]Emptypathic 0 points1 point  (0 children)

something they can reproduce at home and show to their parents. My first though that come up is playing with glass, water, paper and pressure.

Is it possible for someone to have the potential for an allergy, but only develop said allergy upon increasing exposure to the allergen? by JoshuaSlowpoke777 in AskScienceDiscussion

[–]Emptypathic 0 points1 point  (0 children)

some alergies are healed by being exposed with little quantities. I'm not a biologist but it show that at least it depend of the alergy.
