Anonymous asked: IF WAT U SAID IZ TRU THEN WAT IZ A PLASMA GUN THEN B

A plasma gun is something which does not exist yet outside the realm of fiction.

But, I would imagine that it would either: shoot a glob or beam of plasma at the target causing minor skin damage as the ions react with the skin tissue, or minor burns if it is hot.

Or: shoot a beam of ionizing energy that would ionize the air around it and cause minor skin damage/disrupt electrical signals in the vicinity.

I suppose you could call a flamethrower a plasma gun.

Did Stephen Hawking Just Win the Most Outrageous Bet in Physics History?

timotejtherivercat:

idonedivedin:

jtotheizzoe:

The Large Hadron Collider has analyzed enough data to eliminate the Higgs Boson with 95% confidence.

Looks like someone may owe Hawking a beer …

So is this a step toward weightlessness if the Higgs Boson (assuming I remember how it was explained to me correctly) is responsible for determining the mass of an object? Or masslessness? Is that even a thing or would our bodies just diffuse into the air? So many questions, but they all depend on whether or not I understood it all correctly…

nanodash I feel like you might be able to answer these questions. I’m curious as well.

It’s nice to be thought of

First off, that article is more than 2 years old. The Higgs Boson was only confirmed on the 4th July 2012. CERN were having issues finding it right before they…did.

The most recent news I’ve seen is showing the effects of the Higgs Boson on another boson; The W Boson.

Along with the Z boson, the W boson explains the weak nuclear force. It’s one of the four fundamental forces of the universe, along with gravity, electromagnetism and the strong force. This weak force governs radioactivity and nuclear fusion.

ATLAS has reported seeing these bosons scatter off each other at a rate that’s only possible if the Higgs Boson is involved.

But what if you could eliminate it as in get rid of it. Well then subatomic particles would have no mass. So ordinary particles would have no mass. Then gravity would have no effect on you, and you could pass light speed. But don’t go above Warp 10 or you turn into some kind of lizard…thing

Fibonacci you crazy bastard….

As seen in the solar system (by no ridiculous coincidence), Earth orbits the Sun 8 times in the same period that Venus orbits the Sun 13 times! Drawing a line between Earth & Venus every week results in a spectacular FIVE side symmetry!!

Lets bring up those Fibonacci numbers again: 1, 1, 2, 3, 5, 8, 13, 21, 34..

So if we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?!

You bet!! Depicted here is a:

  • 2 sided symmetry (5 orbits x 3 orbits)
  • 3 sided symmetry (8 orbits x 5 orbits)
  • sided symmetry (13 orbits x 8 orbits) - like Earth & Venus
  • sided symmetry (21 orbits x 13 orbits)

I wonder if relationships like this exist somewhere in the universe….

When U.S. attacked itself / Government tested germs, drugs on unsuspecting citizens

nezua:

beemill:

cultureofresistance:

… At least three times in the past, San Franciscans and other Americans have been inadvertent victims of efforts designed to help shield citizens againsts attacks:

  1. In 1950, the Army secretly used a Navy ship cruising just outside the Golden Gate to spray supposedly harmless bacteria over the entire city and its outskirts. Eleven people were sickened by the germs in San Francisco, and one of them died.
  2. From 1956 to 1961, the CIA, in a secret behavior modification program called MK-ULTRA, dispatched agents to test the effects of mind-altering drugs such as LSD and synthetic mescaline on unsuspecting people in San Francisco, Mill Valley and other cities across the country. Many of the victims hallucinated, many became sick and at least two deaths resulted from the experiments.
  3. And from 1944 to 1974, both the Defense Department and the Atomic Energy Commission conducted hundreds of secret experiments in San Francisco and around the country that exposed unsuspecting patients to dangerous doses of radiation, including injections of plutonium.

These secret research projects were supposed to help the military and other federal agencies prepare defenses against biological warfare, nuclear terror and mass brainwashing.

The most dramatic of the biological warfare experiments was the one in San Francisco, where, in September 1950, a Navy auxiliary mine-laying vessel pumped out billions of supposedly harmless bacteria called Serratia marcescens.

Winds from the sea carried the microbes over 117 square miles of the Bay Area.

Eleven patients who inhaled the bacteria were hospitalized for severe urinary and respiratory infections in San Francisco, and one died of bacterial endocarditis.

In testimony before a Senate committee in 1994, Leonard Cole, a specialist in biological terrorism who teaches at Rutgers University, said that for more than 20 years, the Army continued releasing clouds of “simulant” microbes and chemicals over hundreds of populated areas.

The Army’s purpose, Cole testified, was “to assess the nation’s vulnerability to attack with biological weapons.” But by the 1970s, Serratia marcescens was removed from the Army’s list of “simulant” agents because of its dangers, Cole said, and less harmful ones were used instead. 

and then we have the H1N1 pandemic experiment…and its predecessor the so called spanish flu

yes,  this specific article is just for the secret testings that were conducted in san francisco. the united states actually did a lot of these secret biological testings on the public around the country. one that immediately comes to mind are the secret chemical testing done in st. louis on the minorities and poor.

here’s a more comprehensive history of the secret biological testing on the populations in america:

http://www.rense.com/general36/history.htm

The next time someone scoffs at “conspiracy theories” you tell them to study some history. It doesn’t stop here, and no wonder they choose certain populations to run their deprived experiments on.

I would put this under the heading of Scientific Ethics and into the category of Seriously Bad And Fucked Up. Science cannot be considered good or evil. People on the other hand, and even worse, organisations…Yeesh.

Discuss.

Flow Masters

by Michael Keller

Over the last decade, materials scientists have been trying really hard to keep from getting wet. To that end, they’ve made huge strides developing coatings that so thoroughly repel dirt and water, they seem almost magic. Their secret? Recreating the nanoscale structures that some organisms employ to stay clean and dry and to redirect liquid flow. 

Among researchers’ muses from the natural world are the stenocara beetle, lotus and nasturtium leaves, and the wings of butterflies. The National Science Foundation has compiled some compelling visual examples of natural and synthesized superhydrophobic surfaces. See the full video below.

thisuseramehasalreadybeenclaimed asked: Okay, hate to be a bother, but this is sort of a follow up question. I'd their a reason why nails on chalkboard or styrofoamon styrofoam are some of the worst sounds ever?

nanodash:

There’s a reason for everything. For you there are two, a physical reason, and a psychological one.

To explain the physical let’s start with the decibel.

The decibel is how we measure loudness. By which we mean sound pressure, the amount of force per square meter the sound is producing.

0 dB is the threshold of human hearing. 10dB is 10 times the threshold. 20dB is 100 times the threshold, and so forth.

The decibel is a really useful scale if you’ve got a microphone that responds the same to every sound, but our ears aren’t like that.

Our ear canals have resonant frequencies. You know when you tap a glass it rings, that note is its resonant frequency. If you played that note loud enough the glass would shatter. When wind around the Tacoma Narrows Bridge started blowing at its resonant frequency, it brought the damn thing down.

image

Our ear canals exhibit resonance in the 2000-4000 Hz range. Things in that range get amplified in our ear canals and sound much, much louder to us, which is unpleasant. Nails on a chalkboard has a lot of overtones in that range.

But why are our ears set up like that. Scientists have found that those noises trigger a stress response in us. Well it turns out an infant’s cry has a lot of overtones in that range too. So it could have helped keep us alive. We’d want to protect our own. Or shut them up, whatever. Interestingly, if you tell people that the noise is part of music, they say it’s less unpleasant, even though they’ll physically react the same way.

People are weird.

Lnr: I don’t know if it’s still true for me, because your hearing range tends to get narrower as you age, but I could hear tones way into the upper registry when we did an experiment in physics class. It made me feel special right up to the point I had to leave my friend’s kitchen because the noise of her mouse deterrent (which is at a Hz that humans are not supposed to be able to hear) gave me a headache. Fun times.

Vocal ranges

nanodash:

The boyfriend and I were musing the other day about Tenors and Baritones and what those words actually mean and whether a woman can be a baritone.

So I did a little research because, well, scientist.

Wikipedia has it that the three female voices are:

Soprano C4 - C6 

Mezzo-Soprano A3 - A5 

Contralto F3 - F5

And the three male voices are:

Tenor C3 - C5

Baritone F2 - F4

Bass E2 - E4

The middle ones being the most common in both cases. I’m a visual person so I found this representation. I don’t know enough about music theory to make my own so I hope it is consistent with what I have already said.

image

Now, the vocal ranges are split up into male and female. But, I don’t see why, for example, a man with the natural range of A3 - A5 shouldn’t be classified as mezzo-soprano. Then again, I’ve never been in a choir. Any meagre musical ability I have is self-taught (holla for internet harmonica tabs!).

Here is a video of a female baritone. I assure you it is real, though it sounds dubbed. She sounds amazing.

If any nanodashers know more on this topic than I do (not difficult) please educate me and us.

Adam: I knew having a musician better half would be useful. I’m a Baritone-Bass. Go listen to The National. That. That is my vocal range. Bloodbuzz Ohio is the nicest song ever to sing. Most male pop singers are tenor and it’s annoying trying to match them. My falsetto is pretty good as long as I haven’t been drinking. (Usually we sing in modal voice, which uses the full resonance of the vocal chords, falsetto only uses the edges.)

Extra facts, a man who can sing mezzo without falsetto  is called a Countertenor. Above that for men is a Sopranist. But to be able to sing soprano without falsetto is crazy rare, and usually requires endocrine syndromes. If there is falsetto involved they’re male altos and male sopranos. Radu Marian's larynx didn't develop properly during puberty and now he's a sopranist.

kurisimos asked: Hey there! I'm currently doing Physics, Chemistry and Biology at A-level and all of them are tons of fun to learn about, I was wondering what is your next favourite science is? (assuming Physics is first, haha)

nanodash:

Lnr: Has to be Chemistry. Chemistry at the level I did it at is basically math with electrons and I love math. I do like to hear about biological stuff and I am eternally grateful to everyone in that field making me healthier and my life better. But, if it can’t be physics, it has to be Chemistry for me.
