Hi there! I'm doing a project where I will be making 3 ecospheres (ecosphere = enclosed water ecosystem trapped in a jar) using water & substrate taken from 3 different natural sources. I'm hoping that microscopic life will flourish in these jars because my plan next is to study the lifeforms...

Hi everyone! I was wondering if any of you here on PF have heard any news related to the US federal science budget (whether through the NSF, the DOE, etc.). I was curious to see what are some of the research areas that the Biden administration would be promoting, as I haven't heard any news or...

Hello everyone, Last year I took pre calc and that was the highest math I was required to take for my biology degree. I’ve recently became interested in learning calculus. Does anyone have a good online course recommendation I could buy in order to learn all of calc 1? I was looking on udemy...

Hi, I was just attempting this problem and was confused about the calculation process involved. Context: In earlier parts of the question, we calculate the gain ## G ## and effective aperture ## A ## for the parabolic antennae. My Attempt: We are given the power at the output ## x ## in Watts...

Hello all, Now I had graduated from high school, and I'd like to self-study (revisiting) high school mathematics and physics (not for exam). But recently I often saw ads for a local online course platform. Many of the platform's users have been admitted to top colleges, and get better score...

I'm running computational fluid dynamic simulations and am looking into building a desktop. But there are so many options. At this budget, what would you buy? Is it better to buy used CPUs, etc?

Howdy all. I haven't played around with building any circuits recently and so I'm pondering small projects that can be done for around 50 $US, though I'm willing to spend as much as 100 %US on parts. I have a soldering iron and experience using it and some familiarity with components (as well as...

Hey all, I'm a bit of a food geek and a DIY nut and I'm looking to build my own vacuum sealer for as cheap as possible. My question to you guys, is what is the cheapest material I can use that will still withstand the pressure as well as maintain the airtight seal needed? I am looking to get a...

Hi all, I'm justifying asking the forum because I'm currently in an introductory computational physics course that requires Mathematica, and I hope to soon start other computational work. My https://www.amazon.com/dp/B009AEPQDI/?tag=pfamazon01-20's motherboard and hard drive are supposedly...

Working on somewhat of a budget i have the need to shred aluminum sheeting. I have a foundry with a 4 inch crucible and would very much like to shreader the plethora of stock car bodies at my disposal. I'm unsure what Guage the car bodies are but you can fold it by hand. I'll mostly be...

I need ideas to make something for my 6th semester of aerospace engineering. I am stuck with thoughts which either cost me more than my college tuition or consume nearly a decade of my life to make. I am in desperate need of ideas which are cheap, creative, and still a great way of scoring with...

I am a retired climatologist, not a physicist. I am seeking the help of physicists to resolve a matter that has always puzzled me. I shall try to list my reasoning in what appears to me to be a logical order. I will number my statements so that you may isolate my errors more easily. 1. When...

I was wondering if anyone happened to know roughly how much does the average university physics professor spend each year on supplies for performing their experiments. I'm assuming that experimentalists would on average be spending a lot more on equipment than theory people who might only be...

Hello again, My handy optics engineer has left the country leaving me with a problem that's over my head. I need a low cost (i.e. $500.00) solution to produce a circular, collimated, 405nm beam. My beam needs to be within the target diameter (+/-20%) from 0 - 4" from the output lens and...

This is from last week (I was on vacation and then I worked like a dog to make up for the vacation): Nature news article on the subject: http://www.nature.com/news/nasa-funding-shuffle-alarms-planetary-scientists-1.14304 Eric Berger on the subject...

(I am going to attempt a 2nd, little thread before I finish my earlier thread. I want to see if I can practice using PF Rules & Guidelines and FAQ before I wrap up my thread on Autism in Medical Sciences.) In my humble opinion, the current budget crisis in the news likely augurs deep cuts -...

I've never traveled long distance by myself, so I need some advice. I was thinking of doing one of those package deals where I get a flight, hotel, and car rental all at once. Is that the cheapest way to do it? I'm in Florida and I'm going to San Diego for a few days and I want to spend as...

According to a new report out of the Senate Budget committee the 83 programs that make up the category of "welfare" spending have grown in spending by 32% since 2008 and now make up 21% of the federal budget in 2011 a larger portion then any other category on its own (defense,SS,Medicare being...

Why does the EU Stability and Growth Pact sets the specific value of 3% of GDP for maximum budget deficit. Where does the number come from? Why specifically 3% instead of 2.5% or 3.5%? Thank you regards

Hello everyone not sure if this has been brought to the attention of the forum yet but there is a kickstarter project going on called Fight For Space about the neglect of the American Space Program. Go and watch the trailer and let me know what you think. I personally think it is an awesome...

http://www.sciplus.com/singleItem.cfm/terms/16809 I want to get this, since the price is right, and I'm a constantly-broke student- I figure this will provide more hours of entertainment/mental stimulation/social interaction/etc than the same amount of money spent at a bar/video...

I want to learn about engines. Besides reading up on different kinds, what's a good way to get my hands on small gasoline engines, and what kind of things should I do to get some hands on learning? thanks!

Thought experiment (hopefully we don't need to crash a plane to figure this out); Let's say we lift a commercial airliner up to 40,000 feet with a large balloon and then drop the airplane. It will hit the ground sometime later somewhere short of the speed of sound (600 mph or so, depending...

Hard but necessary. Even if Paul has little chance there is important relevant value in this budget plan. Going forward in the GOP primary process this should force more details out of the other candidates which is a good thing. In my opinion the other candidates should have already roughed...

As part of an engineering project I'm in, we've been asked to bale hops on a very low budget (close to 1500 dollars, instead of 15000 like most balers out there). These things take a good amount of force to compact but don't stick together well, so we've figured out easily how to compress some...

Back again to ask another question about test equipment. I'm very new at this so please bear with me. I'm trying to work through this https://www.amazon.com/dp/0521646456/?tag=pfamazon01-20. In order to do a lot of the exercises in the book I need access to an oscilloscope, function...

I am thinking about launching a near space balloon. I'm going to send up a microcontroller with a pressure sensor that outputs audible beeps according to the height data from the pressure sensor. The problem is I don't have a way to transmit this audio data back down to earth. What is the...

So it seems that some states will see more massive budget cuts than others - cuts that may make admissions more competitive and that may decrease the quality of the graduate school experience. Since stimulus funds are ending, this will only make the budget cuts hurt even more. Does anyone have...

I have been admitted to Berkeley and a couple of other UC schools for Ph.D. programs in physics, and I am concerned about how the budget crisis in California will impact these programs over the next few years. Berkeley, in particular, is still ranked very highly, but will this continue to be...

Science fiction often (really, almost always) deals with the possibilities of scientific research that is not constrained by funding requirements. I was inspired to pursue my career from reading and watching these stories, and of course learned a long time ago that this is not realistic...

Homework Statement Build a stair climbing robot. There are no required dimensions. Homework Equations MONEY The Attempt at a Solution I need help brainstorming on some designs of a stair climbing robot that is cheap but yet effective. I have connections with law enforcement so...

I'm looking for as much computational power as possible for maybe 2-3 grand. This looks like a nice setup fit to the purpose, but I thought it would be good to ask and see what other people know or have been doing. (fyi I'm not really a hardware guy myself) Glad for any input!

Homework Statement Your budget is such that if you spend your entire income, you can afford either 4 units of good x and 6 units of good y OR 12 units of x and 2 units of y. A) What is the ratio of the price of x to the price of y? B) If you spend all your income on x, how much x could...

Score one for Perimeter, it would be great if Hawking Radiation is confirmed so he could receive a Nobel and be recognized before his health fails him. http://www.dailymail.co.uk/news/article-1254945/Stephen-Hawking-plans-leave-Britain-Government-cuts-science.html"

Do any of you guys have a PCB router? Do you know of one for less than $1,000?

A balanced budget seems like a good idea to me. How about to you? Currently the federal government borrows MORE than 50% of all the money it spends. I do not see why the average Chinese worker will want to work hard forever just to buy US and Japanese debt paper. In order to balance the...

I've got a simple vacuum distillation setup but no vacuum source. I need to pull 10 Torr. I also don't want to break the bank. I'm considering using an air compressor and aspirator, but I don't know if it will be adequate. this is the...

http://www.time.com/time/nation/article/0,8599,1904936,00.html Interesting article.

The past and current administration have run up record deficits, with a large portion of this coming from foreign nations - China in particular. Our dependence on Chinese credit means that they will have a large say in dictating our policies. Nothing is forcing them to buy our bonds, and our...

Hello all, I was wondering if any of you knew of a really good entry level robotics kit and where I could get one. My budget is probably around $1,000. I'm looking for a kit that has all the essential components, a computer interface, customizable programming etc. I don't know much...

Hello guys, i got a task to design the ground station antenna. I need atleast to figure out G/T of the station. I looked at different link budget analysis, but could not find out how to calclate G/T of the antenna, or atleast how to assume this value. Usually G/T is given, but i got inverse...
