Other Sciences

If you have any interesting facts on science post them here! Here are some of my facts: You burn more calories eating celery than celery has in it. People that smoke a pack of cigarettes every day puts a halfcup of tar in his or her's lungs each year. I'll post more later.

does anybody know the weight of iodine per gram

SamCogar mentioned above... ... to which Phi for All responded... I'll probably not win any friends by saying this, but I'd say Sam is, on this point at least, largely right, and Phi largely wrong -- with no disrespect intended to any of our members. Phi's sentiments reflect a vaguely Popperian view of science, one that is often repeated by scientists who, in many cases, quite understandably due to other commitments, are unable (or even unwilling) to keep abreast of developments in the history and philosophy of science. Popper's view goes something like this: Science can be described as a process of "critical rationalism" or "conjectures a…

(A collection of some thoughts brought on by recent posts and posters. Some of these are touched upon in the FAQ and Pseudoscience section, and these sentiments can be found on other science fora) If you think you've toppled relativity, quantum mechanics, evolution or some other theory with your post, think again. Theories that have been around for a while have lots of evidence to back them up. It is far more likely that you have missed something. Here are some things to consider: 1. You have to back your statements up with evidence. 2. Anecdotes are not evidence. 3. Being challenged to present evidence is not a personal attack. 4. Calling the people…

I recently read a very good book called "The Web of Belief" by W.V. Quine and J.S. Ullian. Its basically a compact introduction to rational belief and an entry point to areas of philosophy, methodology of science, and philosophy of language. Here are some excerpts from the section on the virtues of a hypothesis. I thought it would be beneficial to any aspiring scientist. There are five in all, but I don't have time to type them all up atm, so here are the first three. I will finish them up tomorrow. Virtue I: conservatism: In order to explain the happenings that we are inventing it [hypothesis] to explain, the hypothesis may have to conflict with some of our pr…

This thread has been started after a comment SkepticLance rightly made in the Limit to Growth thread. Basically he felt that he was being asked for sources disproportionately more frequently than other members, and that other people do not cite references as often as he is asked to provide them. While I personally think that's a monster Lance creates for himself, you can't ignore the fact that we don't use references anywhere near as one would expect on a forum like this. Certainly we ask for them much more than we provide them without being asked ourselves. Do we do it often enough? Do we rely too much on poor sources? Do we invoke higher standards for oth…

Without prejudice to anyone, here Is a good example of biasness in science. The question raised begs to be answered in a certain way. If I bring up spiritual-enlightened experiences as a possible causation in the advent of religion, I find myself automatically outside of the parameters set by the question. I contend that this happens more subtly, yet often in science; biasness taking on the form of selective "rational-reasoning" in scientific enquiry. The search of small “t” truths as aptly stated by Eise is then skewed towards a predictable-consensus accepting outcome. A pernicious way of having one’s worldview invite itself at the dinner table. Like minded thinking att…

Some scientists have an interest in ART and the use of ART in conveying scientific ideas that are otherwise difficult to express in other ways . This thread is started to act as a vehicle for such participation. Comments by another Scientific Artist ( anonymous )

I want to have an informed opinion about it, so what do you all know? My theory is that human behavior is so complicated that series of psychological variations lead to changes in natural feelings, such as homosexuality. It is real, but not inborn. The observations to support my theory : Homosexuality has become more common, society has become more complicated, and homosexuality has been aknowledged as an option. Things are more likely to grow if they are a known option. 2nd is Homosexuality in animals, actually i don't really know (read a few articles but nothin definate). Are there any animals that are SOLELY homosexual. Various circumstances (domestication for example…

I just did a bit of thinking, and came up with something: with today's technology, you could theoretically create a (less capable) version of the Enterprise. Here is how it would work: Propulsion: I know that with today's technology, you really can't make warp drive or whatever. But part of it is possible. You have several fission reactors powering the ship. These also power giant electromagnets which suck up all the atoms floating around in space. These are heated up and blasted out the back, like a rocket. Some of the gases could be used for maneuvering, also. You could get to maybe half light speed in a year or so, but you really wouldn't have the ability to do…

Just because something is difficult to prove, that doesn't mean Scientists should just turn their noses up at it. There is a Scientific problem to be solved, so it should be considered. I refer to Classical Homeopathy. The bizarre nature of its mechanism is astonishing, but it is still rational. A German doctor noticed that many substances prepared in the right way produce "symptom patterns" in people. These medicines are acting on the Brain's Homeostatic Centre. Dr Hahnemann simply threw 1000's of these substances at the Brain (using healthy people as subjects) to understand the mechanism of this Homeostatic centre...and he actually solved the problem of…

i was curious if anyone had any input on weather or not melting wood would be plausable in conditions where there wasnt any oxygen, some people belive it would turn to charcoal, but i belive it would very well melt considering, you need 3 main things to have a fire. fuel oxygen and a source of ignition, take away one and it should not ignite into flames therefore at a certain tempature, it would melt.

and yellow brown on Mars?

Why infants and children died at a horrific rate in the Middle Ages? Quote For starters, infants and children died at a horrific rate (some say up to 1/3 of all died before the age of 5) Quote https://www.sarahwoodbury.com/life-expectancy-in-the-middle-ages/ Why did infants and children died at a horrific rate in the Middle Ages? Most people only lived to mid 40s. What happen in the Middle Ages people died so early? Was there just more bacterial and virus back in that time?

I thought it would be fun to make a thread of annoying myths. I'm sure everyone is annoyed by myths that the naive general public sometimes belief. Ok some of mine: There is no gravity in space (when the astronauts go up) Humans only use 10% of there brain. (I guess this is debatable) Seasons are caused by how far away from the sun earth is. Creationism (I had to say it) These are all I've heard people say and believe to be true. I bet everyone has heard some.

Hi, I'm trying to power my 40 watt lightbulb, and I've been at this for a bit, and was told this morning I would need 22,000 "C" batteries, which seems like it would make my lightbulb explode... Anyway, my standard C battery I am using has 1.5 volts and 7.5 amps when I tested it. Now, my first possible pitful of not being sure is, if I stack these batteries together, I know the volts will just add, but will the amperage stay constant? Now, assuming the amps did stay relatively constant, I figure it would take 5.3 volts to power my 40 watt lightbulb. This is using the following equation: P = iv 40 = 7.5x x = ~5.3 Now, assuming 1.5 volts per battery,…

I promise I'm not trying to make a point with this. I'm just curious as to how you feel the scientific community should treat these two groups that oppose basically what it as a body is saying. Now obviously there are some global warming deniers (or anthropogenic global warming, or whatever semantic games you want to play) and even a few Creationists on this site, so perhaps you're going to have a different opinion than us drones, and I'd be interested to hear those too. Is denying the scientific consensus on the origins and development of life and the universe analogous to denying the scientific consensus on anthropogenic climate change? Is one position more valid th…

There is not a day that goes by with out the media going on and on about going to the moon or mars!!! Well it serious not going to solve problems of colonization of the moon or mars. It not going to solve overpopulation problem. It not some thing the middle class can have enough money on one way ticket to the moon or mars. Even the upper class will not have the money for a one way ticket to the moon or mars. So it not going to solve the overpopulation problem. What is with the government and private sector pushing this trip to the moon or mars in 10 to 15 years. When there is no spacecraft that cost effective? Any spacecraft they have and in the research …

So I have been studying evolution and seeing how people from different parts of the world adapt to their enviroment. So the data I have gathered so far is that humans with a darker skin tone gives them the advantage in areas closer to the equator, people with lighter skin tone are adapted to lower light levels further away from the equator. Here is the further information. "Surprisingly, the team found no immune genes under intense selection, which is counter to hypotheses that diseases would have increased after the development of agriculture. The paper doesn’t specify why these genes might have been under such strong selection. But the likely explanation for t…

Lose the flower garlands. The way I see it is that even in our earliest histories humankind was "towards" trends, which is always hurtful. Our food regimen haven't ever really gotten better, only more conventional, at the expense of the furthest reaching convenience. In other words, from the earliest ages we've always been toward better medicine at the expense of authentic wholesome foods. That's just my point of view. That's the way I would have it; and the thing is, that's what I'm towards. For example, my refrigerator is shut down. I've discovered (as a personal convenience) fermentation is always a safe preservative method. And folks love my Mediter…

hm the other thread on this subject got far to heated for any meaningful information to be gleaned from the thread. However the thread also had some interesting ideas in it which I think are worth a closer look at. Just to reiterate some of the points from theprevious thread which seemed to have gotten garballed. Peakoilman stated that Geologists had predicted the peak of American oil production in the 1970's, this prediction came true. Also he stated that a number of oil companies/geologists are predicting that oil, and coal are about to peak and or hve peaked in the majority of the world. I am very interested in 2 things happening in this thread. …

EDIT: I accidentally placed this in the wrong section. Goddamnit. Can a moderator move this? Recently I began a new inquiry into anthropogenic global warming/climate change unlike my previous ones. This time I had both experience debates provided, and a new perspective to explore that my earlier research queries blessed me with. My original stance was that of some confusion. As I wasn't entirely sure of the whole picture. Debating this on various forums helped substantially, and also aided in the gathering of information required for me to delve deeper into the anthropogenic climate change theory. - My first links will deal with the history and development of…

Hello. Q1. How far and fast can a neutrino travel? Q2. How do we know if neutrinos come from our sun, when neutrinos can pass through all known matter? Could they be coming from another star instead? cheers.

First of all, I'm sorry if anyone thinks this is in the wrong topic. I looked at all the topics, and I couldn't decide because different people will have different opinions about this post. Some may believe that this is fictional, or related to religion. However, I believe that this really happened, so I consider it to be real science. Several years ago, there were a few teachers in an elevator at a college in Gettysburg. They went down into the basement for some reason. When the doors opened, they found themselves back in the Civil War! The basement was being used as a hospital. There were injured Civil War soldiers everywhere. The teachers pushed a button…

Hello dear musicians, music lovers and everyone! I'd like to describe fingerings for music instruments with tone holes (which almost means woodwinds) and the associated mechanics. My goals for these fingerings are: Open all holes below the height-defining one, at least on the two first registers; Have no difficult key nor sequence of notes; Not need to close a hole and open an other simultaneously, at least on the two first registers. That's a difficulty of the flute; Need few tone holes regularly spaced and reasonable mechanics; But I don't primarily address the ease or possibility to disassemble the instrument. 1) and 4) make the sound quality more even and let build…
