Hello all... My story is very complicated, I'm a quite disturbed individual... See, when I read an interesting article in a newspaper or a pop-science journal I immediatly get melancholic and depressed about the fact that I can't get all the knwoledge in the world. Socrates pretty much summed it up by saying that the more he learned, the more he realized how little he knew... I know that I will never be able to know EVERYTHING, but I would like to die trying. For this, I need to know what areas of knwoledge humans developed over thousand of years. I'm talking about everything from religious studies to arts and literature... Wikipedia has those "portals" on many…

the moon did that. DINOSAUR EXTINCTION i've always looked at the moon and wonderd if dinosaurs saw the same view. the world was a very different place, then, and i wonderd if the moon might have looked different. this started me thinking "did the moon ever spin?". so i asked nasa this question. they replied me and said "it did spin and stopped 200 million to 2 billion years ago." so then i thought "the solar system is 6 billion years old, their guess is one third of all time, maybe this isn't a much looked into question. TIDES : everybody knows the tide and the moon are linked but how? the thinking at present is that gravity, from the moon, pulls at the…

Unable to find any proper justification to place this in any other category, I suppose this shall suffice, however I have a question. I'm thinking, for an upcoming science fair, to do a project regarding a possible method to stop shoreline erosion. I've delved into the basic concepts, chemical and physical weathering, transportation erosion, on the general topic, however, I find myself lacking ideas. Asked my teacher for help, which I gained little of, though he gave the hint of looking up how the direction of shoreline currents play an active role. I searched on google, but found little. Any ideas perhaps on the subject. Information is important, however, might anyone a…

in my efforts to make the perfect plant food for my Chili bushes, I was in need of some Phosphate (I have no Phosphoric acid left in the lab and was fresh out of Coke Cola to extract it from too) so I though I`de make some I had several boxes of safety matches in the lab drawer, so I decided to peel as thin as I could the 1`st layer of paper off the cardboard match box that contained the red Phosphorous. I put it in a test tube and heated it over a blow torch (bunsen burner), with my thumb gently over the end of the tube, all went well apprt from paper)wood) distilates inside the tube, but all chared nicely, freeing the phosphorous. when I took my thumb off the end o…

How would one change a male species into a female of the same species through either gene splicing or gene therapy or would it be more plausible to use another genetic method? im an armature self taught geneticist and would like receive more information on the subject I am researching please no rude comments. If you do post rude comments i will have them taken off by admin.

Has anyone read Wolfram's A New Kind of Science? Thoughts?

A New Manhattan Project for Clean Energy Over the past year many luminaries have made clarion calls for a concerted effort to solve the energy crisis. It is a crisis, with 300 million middle class Chinese determined to attain the unsustainable lifestyle we have sold them. Their thirst for oil is growing at 30% a year, and can do nothing but heat the earth and spark political conflict. We have been heating the earth since the agricultural revolution with the positive result of providing 10,000 years of warm stability. But since the Industrial revolution we have been pushing the biosphere over the brink. Life forces have done this before -- during the snowball e…

I bought a small torch light bulb one hour ago as my old one was faulty after I connected it to a 15V battery. Now, it is quite different from my old one, not exactly the same in some manners. For the old one, it can endure a voltage of 2.4V and so does my new one. However, a label " 0.8A" was on the old one but "0.5A" is on the new one. What does it mean? I guess it probably is the ampere of current passing through the circuit with a voltage of 2.4V with the presence of this bulb. I guess so. By the way, I have no idea on which bulb can give a brighter light. I think the new one could be brighter as the resistance is higher, am I correct?

This is my theroy (sorry if it's not a new idea) on why time travel may be theroreticly imposible: 1. It's the year 2006 2. I move myself 20 years into the past (to 1986). 3. I stand in the feild that was here before my lab was built and look around for a moment. 4. I go back to 2006. Even the verry small amount of change I made in 1986 (apearing in the feild, looking around, disapering) is still change and will slightly alter the circemstances in which I built my time machine and went back into the past in step 2. Therefore step 2 will happen in a slightly difrent way and so alter the way step 3 and 4 happen Therefore step 2 will happen in a slightly difr…

When you learn a new concept, such as Einstein's theory of relativity, sleep on it. After initially reading or being told about whatever it is that you're learning, go home, fall asleep, and then dwell on the matter at hand upon waking up. Many great scientists have reported using this technique. The idea is that the newly found knowledge simply marinades, making it easier to understand and in turn allowing more to be learned from it. Just dwell on something and sleep on it a few times. YOU'LL GET IT EVENTUALLY.

I am confused about is the study of atoms and particles under physics or chemistry..........? In my science dictionary, it is the physics section which tells about the structure of atoms........ but in my school, it is chemistry subject which teaches about atoms and particles............ Can any body explain this how and why? More over, please tell me the true definition of physics and chemistry for better understanding...... Apreciate for the responds.......

An abstract: Can there really be people who eat more than others and have a lower daily caloric expenditure and still weigh less? Perhaps many have wondered that, since conventional observations point towards that. There are people who eat more, spend fewer calories, and weigh less on the scale. This seems to contradict the calorie paradigm, which maintains that it is in turn based on physics that maintains that the universe cannot create or destroy matter or energy. However, something that some seem to have been ignoring when addressing this topic is that even building a building requires energy. If you build a building you probably use more energy than if you…

Some nice person bought me a "Book of Useless Information" a while back and one of the entries caught my interest: H2O expands as it freezes and contracts as it melts, displacing the exact same amount of fluid in either state. So if the northern ice cap did melt, it would cause absolutely no rise in the level of the ocean Equipped with just a GCSE in Dual Science that was news to me (the bit about oceans - not the freezing and contracting) - is there anyone more learned in these matters that could corroborate this? Also (question #2) I remember back in the 1990s there seemed to be a group of scientists who said that a significant portion of the effects of gl…

recently, i learned that the atmosphere is 78% nitrogen, 21% oxygen, and 1% other stuff like carbon dioxide, sulfer dioxide, etc. I was wondering, what will happen to humans and other animals if the air was pure oxygen? Would animals die off (from ther air, not by lack of food because plants will die off), live better, or will it stay the same? If anyone knows please tell me.

Okay, so, for this project, I'm doing a regression for the data I measured and the data that was generated(an estimation made by a computer). I am also trying to find the rate of error between the two values. So, when I try to find the error, do I measure how far away the generated is from the measured, or how far the ordered pair that they make up is from the closest point on a 1:1 line? Or, am I going about this completely wrong? x3 Thanks for any help you can give me!

I have a question. Suppose that we have two nuclear devises of equal power. The first explodes 300 metres over the surface and the other many miles away in the surface. Which explosion will be responsible for the bigger pollution of the environment? Why? I have hear that this that will expode in the surface will be responsible for about 10 times bigger pollution from the other. Is it true? Why? Thank you.

Scenario: Miniature & Parallel Universe The following question originated at a dinner party among friends. There was an interesting and educational variety of answers. By the readers leave I’ve transferred the question to SFN Question: In a universe parallel to ours, exactly the same in every way; with all of the galaxies - including the Milky Way, and our solar system with all our planets as they are, including earth and everything on and within it and including its inhabitants and the molecules, atoms, electrons, nuclei, photons - except: that this ‘twin universe’ and all of its contents was one thousand times smaller than the universe we in the here and …

I've been assigned for a school thing to find out what hydrofluoric acid can be contained in and why. I've found that it can be contained in polyethylene containers, now I just need to find why. I haven't been able to do so yet. Does anyone know the reason for this? Also, it can't be contained in glass containers because it is one of the things used to etch glass, I need to know why this is as well.

so if 1000 earths were formed at the same time, and everyone of them had life and everyone of them had humans like we did, say 100,000 years ago in 2025, would all 1000 earths be in the same place, ie.. same inventions etc would electricity have been invented on all 1000 earths be, even if it was at different times

YT, do you have every method for making every single compound on this planet?! I was reading ur threads, some showed me how to make copper sulphate, sodium iodide! Did u actually learn this or just found it form experience? Very impressive! Good work!

Sometimes, we forget that science is not only in labs and textbooks it’s all around us. From the way soap cleans our hands to how plants turn sunlight into energy, tiny scientific principles are shaping our daily lives. What’s one simple science fact that recently amazed you in your everyday routine?

I just watched the '9/11 conspiracy video' and I have to agree, there isn't much truly 'hard' scientifically empirical evidence, save for one fact. The documentary says kerosene burns at 1120 C and that isn't enough to melt either steel or titanium, and you have to keep the heat on it for several hours. But they say that the kerosene the jets used as fuel weakened the reinforced steel they used in the WTC. They have a quote from an engineer at the company who certified the steel in the 70's and said it should take over 3000 degrees for several hours to cause them to be that weakened enough to cause the NEAR freefall collapse of the WTC. Isn't that something y…

The question of whether or not anything or consideration really exists is an endemically popular but hardly stimulating tonic for cynically industrious ennui. A lot of seriously proffered equivocation occurs in glib denouncements of the existence of anything, particularly with regard to whatever spatial issue of 'truth': and/or time. As though Plato was not a student of Socrates, and that each and both of them did not long ago put to rest, the rasberry dispirited vanity of such allegedly 'unanswerable questions & unresolvable riddles'. The discarding of 'reality' has long been a ploy for those who disdain the responsibility of recognizing and acknow…

Yesterday one of my friends told me that some science people had discovered a perfect empty square inside the Ayers Rock, and of course they had no seriously chance to explain this phenomenon. He read it in a International science magazine, he say. Anyone who can give me an article or just tell me if this is true or not? Another thing which is connected with the empty square in Ayers Rock should be a testement of something called "the pain profet" or something similiar to that. I have tried to search out the Internet with many different way of writing this, but can't find anything. I'll hope some of you may help me.

Hello, Here is single edged knife. Consider spine= blunt end blade belly = sharp cutting edge Here is the wound Now the really pointed end at the left side of the wound, is it created by blade tip or the blade belly (sharp cutting edge). This might be obvious but I'm bit confused at how this wound is created, when I look at double edged wounds. Thanks Double edged left, single edged right.
