Calling British Amateur Scientists!

From the BBC: Snail "GPS", Facebook psychology and crowd dynamics at music gigs: these were just some of the ideas submitted during last year's search for "citizen science" projects. Now, Radio 4 is launching its search for the next BBC Amateur Scientist of the year. A panel of judges, chaired by Nobel Prize-winning geneticist Sir Paul Nurse, will select four finalists. The shortlisted entrants will then have their ideas turned into real experiments, with the help of a professional scientist. Last year, 70-year-old gardener Ruth Brooks won the award for her research into the homing distance of garden snails. She found that Helix aspersa, the common garden snail, can find its way home from up to 30m away. But for gardeners to be sure that their snails will not come back, they should be moved over 100m. Do you have a cool idea that could be turned into a proper piece of scientific research? The judges for So You Want to Be a Scientist? will be talking about what they'll be looking for in this year experiments on Material World, Thursday 29th September at 4.30pm, Radio 4. Entry is open to anyone over 16, who is a resident in the UK and applications can be submitted online until 31 October.

Science fair ideas

Please help me think of a science fair topic for my science fair in 7 weeks. I need something that has something related to the environments because that is what is the judge this year is looking for. If you could help me think of an idea it would be great.

Tomorrow

Tomorrow is the Science Fair at my school and I'm not finished yet. My aim is, Will Climate Change Affect The Growth Of Grass In The Next Ten Years? I've done the testing and I'm writing the conclusion. I need to know some plants that are sensitive to temperature changes. I have already searched and can't find any (I must have very bad searching skills). I also need to know what kind of chemicals that plants use. I'm kind of panicking right now!

Does yoga do what it claims it can?

Hi people!  Does yoga really do what it claims to?  Here in my place, my parents and elders claim that yoga can prevent diseases(like cancer, or blood pressure variations, diabetes etc), and even help in curing of above mentioned diseases. Is it really true? If yes, what is the mechanism behind it? If no, then what does it really do?

Is homeopathy a proven science?

Hi again people! This is yet another question to which i have to get definitive answers.  Is Homeopathy a proven science? Alternate medicines like homeopathy, Ayurveda are so common in my country, that most people tend to believe them blindly and are ready to take "medicines" from them for all kinds of problems, from Not-really-worth-bothering stuff like common cold, to moderate stuff like diabetes, and even extreme life threatening cases like cancer. To be honest, even i didn't bother looking into them much and few years back, i thought MAYBE it does work, after all so many people take it. But in my recent years, i have developed a condition known as psoriasis, so i had to start bothering as most people force me to take these medicines, as thus far, "Allopathy" does not have treatment to this condition. But alternative medicines claim they do. i was getting a little skeptical. When i started really questioning stuff, i didn't get quite satisfactory answers. Doing a little research on my own, i have seen videos from one of my favourite intellect, Prof.Richard Dawkins. He says that homeopathy is mostly bogus. When i question this to the people around me, specially the elders, they just throw it out of the window, and tell me that i am too young to understand stuff, and people who claim things know nothing about these kind of stuff. It is the same in case of Ayurveda. How far are these claims true? Is homeopathy(Alternative medicine in general) a bogus? If that is the case, then why is it so famous? Why is the community adopting it despite all this? Or have i misunderstood the concept? Do pardon me if my question was too long :)

My Theory for How Gravity Works

So I've never really found out how gravity actually works, why it happens. But a few days ago I had a epiphany. I don't know if I spelled that right. So everything is at least a little bit magnetic, even stuff like wood, no matter how little. So all of this stuff would be attracted to all the other stuff electromagnetically, right? Even a little bit? So when you get huge amounts of this stuff (I'm thinking planets here) there is enough electromagnetic attraction to pull it together, and voila! We have gravity! Plus when you have planets, there's tons of stuff like iron and other metals and metaloids, that could be very strong, magnetically. So if I'm wrong (which I probably am), can someone explain how gravity actually works to me? I'm constantly thinking about stuff like this, I get theories like this every once in a while, many of them right. But not this complicated, more stuff like figuring out how air pressure and vacuums work, but basic principle stuff.

Citizen Science contest

Hey! I have entered 1 of my instructable in the sci-starter contest. I wanted to know one thing that the contest states.It says - "Select one or more to solve or come up with your own creative solution to a challenge you face as a citizen scientist!" So, from it I perceived that if I have a problem as a citizen contest I can submit an instructable solving it. So, I submitted 2 of my instructables- https://www.instructables.com/id/HOW-TO-TEST-YOUR-TRANSISTORS-WITH-YOUR-MULTIMETERS/ https://www.instructables.com/id/HOW-TO-CALCULATE-RESISTOR-CERAMIC-CAPACITOR-VALU/ But I  got both of them rejected. As the other instructables in the contest include how to make a motor,how to make a carrot cannon,power your home with steam.etc. I do not think either of them is a solution to any problem. Thank you

2 transistor Crystal radio amplifier kit - shortwave science fair

This kit is 5.00 dollars . To order send email. Then send check.  The amplifier  has the parts soldered on top of homemade circuit board. It is tested . I listen for KCBS, KGO,kSCO and several other stations with only a small ferrite on a crystal radio..  Only the circuit board is included.  The coil and tuning capacitor are not included. Many coil and variable capacitor combinations will work up to about  13 Mhz.  There is a small wire near the output which provides feedback when it is moved towards the input.  Each station is tuned individually as the feedback is different. Wrap several turns around the input coil (not included).  The variable capacitor is in parallel with the coil. The shortwave coil can be a 1 inch diameter with 13 turns of narrow wire. Stations I pick up are Radio Havana Cuba,  Radio New Zealand , Church and amateur. There are some cautions. It could include cutting tape for your circuit design.  The shortwave requires an external antenna. Schematic included. Crystal earphone is not included. Another transistor can be added for speaker  or 8 ohm type earphone.

Project for vector calculus

Hello there, So, for my project in Vector Calculus: The suggestion is that we pick a certain "curve" within a country road. We are to log longitude, latitude and altitude while we drive this "curve" for approximately 15-20 seconds. With the data from the latitude-longitude-altitude "logger", we are to perform the various vector calculus principles we have learned in class. Instead of driving the road, I would like to attach whatever latitude-longitude-altitude logger to a boomerang, and get my curve through flight. Does anyone know which sensor I should be looking for? A bit about me: I am currently an electrical engineering technician in product development for a motor-controls company. I mostly test hardware/software, which is designed by our in-house engineers. I am very comfortable with soldering, visual inspection of PCBs, schematics, and general electrical engineering knowledge. Does anyone have a feasible idea for getting a gps unit onto a boomerang, and be ale to transmit the data to me in real-time? Thanks in advance.

What NOT to do.

Not sure whether this is a contest idea, or just a philosophy, but the idea that we learn more from our mistakes rings true.  Although it might be tediously long at times, I'd kinda like to see some -ibles that include the messy details of attempts that didn't quite work, what was learned, and how. Sometimes tangents xyz come out of an attempt to acheive abc. y'know- the happy accident.  Examples?: I was annoyed with Apple for making a keyboard with light grey lettering on white keys. I like to dim the lights, and am not really a touch typist. So, I photocopied the keyboard, increased contrast, and printed this onto transparent sheet with adhesive backing (available at a photocopy place. Fed-ex, kinkos, i don't recall)  Turns out that the ink on those copies is on the top surface of the plastic. After cutting out my qwerty stickers, I found that the ink wears off the surface.  Not only that, but after peeling the stickers off, the goo remains. (sigh)   So, if u use this technique, put clear tape over the clear photocopy. I just bought a microwave with grey on black keys. I may havta explain to the copyshop why I'm photocopying my microwave. ;) Any other examples?

Science Section

Is it just me, or is the science section as a whole getting suckier?Science is my best subject. I get A's in school, avidly read Scientific American and other science magazines, read physics and astronomy books, and once gave a 45 minute speech about the viability of Algae as bio fuel (Instructable coming soon) for a science project. So obviously, when I first joined, I ate up the science section, reading through great instructables, like the ones created by egbertfitzwilly (oh, shut up, you know who I mean) and other great instructablers. I loved them. Now however, it seems to be full of toy guns, electronics projects that belong in tech and recipes. Goda**it, just because your beer recipe uses yeast doesn't make it a freaking science fair project! If your instructable doesn't need a second category, DON'T GIVE IT A SECOND CATEGORY. Whoa, that was hard, eh? For instance, this. Its not a bad Instructable, sure, what what the heck is it doing in the science section? How about the ginger beer instructable? Or smart LED's? Or a coding machine? I want, and I'm sure others want, more Egbert and Nurdrage styled instructables, with cool stuff that makes us go "Whoa" and want to do it ourselves, not some of the random junk that people seem to throw in to get an extra 3 hits.

Good science idea

Hi, could someone make an app that, maybe uses a similar technology, to be able to identify plants, animals, and fungi? You could make it into a database where the users of the app put in the information, much like Wikipedia, so its ever evolving. I'd really like to be able, in my wood travels, to take my non existing iphone, and scan an organism with it and know all about it. I feel that that would be awesome.

Where do I get my science?

Since joining Instructables at the end of September, I've jumped into several discussions of scientific topics, not all of which are directly related to my specialty (experimental high energy physics). Why should I pose as any more of an "expert" in these different areas than anyone else?Well, I shouldn't (pose, that is). In the interests of disclosure, I thought I'd post some of my general sources for scientific information. I'm also hoping these might turn out to be of interest to other I'bles community members. PhysicsFor current research, I skim the arXiv preprint archives every day or two and see what's out there. These are technical papers intended for peer-reviewed journals, so they are generally not accessible to the lay public.Physics Today This is a "general interest" publication of the American Physical Society, intended for physicists but not for subfield specialists.PhysicsWorld from the IOP, similar to Physics Today. Non-physics ResearchNatureScienceBoth are peer-reviewed journals, but cover a full range of fields, including physics, chemistry, biology, astronomy, and more. Popular Science NewsNew Scientst Generally good, but also includes a sprinkling of non-traditional speculative articles, so be a bit on your guard!Science NewsScientific American I actually get this one on paper, in the mail...I also highly recommend the Science & Technology articles in The Economist. As I've commented elsewhere, they have some of the best (both in language and in technical detail) journalistic coverage of science that I have found anywhere.Update 15 Nov 2008: With thanks to GorillazMiko,Science Daily Books, Books, BooksI read. A lot. Stephen Jay Gould, John McPhee, Oliver Sacks, a wide variety of "popular" science books.

A late newsflash - Creationism being taught legally.

This just turned up in my email:***www.NewScientist.com - NEWSFLASH*** On the 28 June, The Science Education Act was passed as law in the State of Louisiana. This piece of legislature now allows teachers in this US state to present non-scientific alternatives to evolution, global warming and cloning – including ideas related to intelligent design. Opponents fear that Louisiana teachers are now free to present evolution and other targeted topics as matters of debate rather than broadly accepted science, and could have national implications.

Science of Irrational Behavior

A lovely book review from The New Yorker. The book sounds like fun:In "Predictably Irrational: The Hidden Forces That Shape Our Decisions" (Harper; $25.95), Dan Ariely, a professor at M.I.T., offers a taxonomy of financial folly. His approach is empirical rather than historical or theoretical. In pursuit of his research, Ariely has served beer laced with vinegar, left plates full of dollar bills in dorm refrigerators, and asked undergraduates to fill out surveys while masturbating. He claims that his experiments, and others like them, reveal the underlying logic to our illogic. "Our irrational behaviors are neither random nor senseless -- they are systematic," he writes. "We all make the same types of mistakes over and over." So attached are we to certain kinds of errors, he contends, that we are incapable even of recognizing them as errors. Offered FREE shipping, we take it, even when it costs us.Another review from The NYTimes with an entirely different set of examples. This is definitely starting to sound like a fun read.

Subscribe....For similar stories, visit the Comment and Analysis Topic GuideMOST scientists want to see more science and technology in the media, but we're making life hard for ourselves by forever criticizing each other's efforts or denouncing journalists and film-makers for not portraying science in ways we approve of. While healthy debate can improve science communication, I think we could all shut up a bit, and stop the more rabid criticism altogether. I include myself here....If you're still troubled by how others communicate, why not spend less time ranting and get out there and communicate in ways you do like?
