rallain | March 17, 2009Dear Ruff Ruffman,
My kids really like your show. However, there is a problem. You promote it like it is science, but the content keeps having mistakes in it. Previously, I pointed out your mistake about in infrared thermometer (if can't remember, you said the thermometer measures the temperature with a laser. In fact, the laser is just used to aim.)
So, you see, I don't just like to randomly attack people. The problem is that you are saying "hey look at science" but your science is wrong. I suggest you either a) stop pretending to be a science show or b) get a science advisor (I am…
rallain | March 6, 2009Temperature is a pretty weird thing if you think about it. How do you best define temperature? Let me go ahead and give you my favorite definition:
Temperature is the thing that two objects have in common when they have been in contact for a long time.
Yes, that is a good definition. Maybe now you can see why temperature is weird. Doesn't it have something to do with energy? Well, something - yes. Let me take an example. Suppose pour some hot coffee into a paper cup (I use paper because styrofoam(TM) is trademarked). Further suppose that this is super hot coffee from McDonald's. Can…
cmooney | March 4, 2009Mike Dunford has the details, based on Congressional Quarterly's reporting. There are apparently multiple senators blocking two of Obama's key science appointees from taking their posts. This is outrageous--a totally new kind of "war on science"--and we need a full court press. Details here.
cmooney | February 25, 2009Obama really laid it down last night, no? He clearly said that even with the economy crushed, he wants a cap and trade bill to cut greenhouse gases this year. I know it's a campaign promise and all, but I seriously wouldn't have been surprised to see some de-emphasizing of this priority in light of the current financial situation.
I've done a major article about the prospects for a cap and trade bill that's coming out soon, and don't want to tip my hand yet, but suffice it to say--this is going to be a hell of a battle. A lot of senators are going to be very worried about the economy, and…
rallain | February 24, 2009Quantum mechanics is not my area of expertise. Really, I have no area of expertise. However, I think it is time to bring the whole photon thing back up. Yes, I know I was a little harsh before. Maybe I should start over.
First, models. Yes models. I think science is all about models. Scientists build models that attempt to agree with observations. These models could be mathematical, physical, conceptual or numerical (like a computer program). For example, take Newton's Law of gravity (which isn't really a law). It says that the gravitational force between two objects has the…
cmooney | February 18, 2009There is this strange idea out there that George Will is a smart person's conservative. Maybe it's the bow-tie.
But if you read his latest, scandalously hackish global warming column, you realize that nothing could be further from the truth. Any person who respects thought, ideas, knowledge, or the contemplative life--any person, in short, who deserves to be called an "intellectual"--could not write such a column; because any such person would have undertaken to learn something real about climate science before writing about it.
Yet this Will manifestly has not done, or he could not make the…
cmooney | February 13, 2009Science Debate has done a great analysis of the science funding that has emerged from the House-Senate reconciliation process on the stimulus bill. For the most part, science funding was restored through the reconciliation process: $ 3 billion for NSF; $ 2 billion for DOE Science; $ 5.4 million for DOE research on efficiency and renewable energy; and 10.4 billion for NIH.
You can check out the full analysis here. Assuming this bill gets to the president's desk and is signed--which seems a fairly safe assumption at this point--then this is great news for science and American innovation.…
cmooney | February 11, 2009We're pleased to repost the latest email from ScienceDebate:
Dear Friend,
Last Friday you and others in the science community took action and helped to restore $3.1 billion in cuts to science that had been planned in the Senate compromise version of the stimulus bill. That was a good victory for U.S. Science, but it was just the warm-up act. Now we all need to come together as a community for the real show.
Even after the $3.1 billion restoration, the final approved Senate version of the stimulus bill falls far short of the House version when it comes to science and technology. You can…
cmooney | February 5, 2009My latest Science Progress column takes on those, like right wing columnist Deroy Murdock or Lou Dobbs, who persist in trying to claim that winter weather refutes global warming. There are so, so, so many reasons this argument is dumb; and yet at the same time, who can dispute that the prevailing weather at a given time does highly influence the trajectory of the climate debate?
So while it's intellectually silly to pretend that winter weather refutes global warming, it was also strategically silly to hold the giant United Nations conference in Copenhagen this December.
You can read the full…
rallain | February 3, 2009People say I am picky. Ok, sometimes I am. But somebody has to stand up for what is right and just. Maybe I am that person.
Please stop using the word force if you don't know what it is.
There. I said it. You can attack me now.
It wasn't just one thing that got me fired up. It was two things. First, I read this article on physics and football (Physics of 'The Hit' from the NY Times). If it was just this article, I would have let it go and moved on. But no. One of my kids just happened to be watching MythBusters (We all love MythBusters) and there was a discussion that used the term…
cmooney | February 3, 2009The American Physical Society is asking folks to email Congress in support of the science parts of the stimulus package. The House version of the bill was very generous to science, but there's a concern about what the Senate version and the reconciliation process will end up with. So weigh in now; the tools to do so can be found here.
rallain | January 30, 2009I said I would come back to this, and I am. I am a man of my word. Yesterday, I posted a link to a video of this really cool water rocket thingy.
How does this work? What is the physics going on here? I think this can be best explained with the momentum principle.
Let me start by pretending like I have some object that shoots out a piece of water (or really it could be anything). Also, let me pretend like this is in space ore something where there are no external forces.
Above is a before and after picture. Initially, there is something (the box) with water inside. Through some process…

I'll have more to say about the whole experience in my next column....thanks to everyone who wrote in with positive words about the segment.
cmooney | January 27, 2009You can watch it here. Tons of funny stuff in Colbert's segment on science, which starts roughly at 6:15 and runs to roughly 10:45. I was on for about three minutes, and was instructed: "No monkey business. No evolution."
Of course, even though Colbert plays a rightwinger who thinks with his gut rather than his head and doesn't trust book learning, the truth is that his show features a ton of science content and, indeed, is doing vastly more than most other parts of the media to improve the role of science in our culture.
I was thrilled to be on.

With inauguration day in mind, there is no doubt President Obama has made excellent choices for his science and energy team, but as I wrote over at DeSmog, do not declare victory quite yet... There are also signs that the administration could falter when it comes to dealing with global warming in the strongest possible fashion. In particular, other high level picks suggest there may be serious impending battles in the White House over climate policy. Here is an excerpt:
While global warming may be the world's greatest threat, the climate in Washington, DC is probably tepid at best toward…
rallain | January 19, 2009I just can't pass this up. One of the chemistry majors had a complaint with the power company. After an unusually high previous power bill, they checked the electric meter half way through the month. The meter said they had used 90,000 kilowatt-hrs of electricity. That is a lot of energy. It is also a lot of money. If I estimate 10 cents per kilowatt hour (the prices varies in space and time), this would be a $9,000 bill.
So, what is the deal? Is it a broken electric meter? Could be. If it is not, maybe it is a short. Shorts usually blow a fuse, but if it were an older house, could…

rallain | January 8, 2009Here is an article from Wired.com that talks about a used cooking oil generator. It's a really neat idea in that the oil is right there anyway. Here is my problem - from the article:
A new garage-engineered generator burns the waste oil from restaurants' deep fryers to generate electricity and hot water. Put 80 gallons of grease into the Vegawatt each week, and its creators promise it will generate about 5 kilowatts of power.
If you put 80 gallons of grease into the thing, that has a finite amount of energy. 5 kilowatts tells you the rate the energy is created. This would be like saying "…
rallain | January 7, 2009I saw this video posted on Physics and Physicists:
It reminded me that I had at one point tried to analyze this. I had actually posted something about this on the first generation of my blog (which no longer exists). I have found the analysis, and here it is from the archives. Thanks ZZ for reminding me.
Could this be true, or is it fake? I started to do an analysis of the trajectory, but I found the following frames:
Look at the guy's back. His back starts moving before the water bottle rockets. It must be some type of cable pulling him. If the rockets were propelling him, the rockets…
rallain | January 3, 2009I finally saw the movie Iron Man. It was good. I feel that I am qualified to evaluate the movie. When I was in high school, I was totally into comic books. Mostly Spider-man, but I still have a significant collection of Iron Man comics. Ok, now you know I am not an Iron Man attacker. I will now attack the movie. Sorry, it's what I do (remember, I already said I liked it). There are several things I could comment on, in fact I recall some other blog talking about the physics of Iron Man.
My attack will center on the scene where Tony Stark (Iron Man) escapes from captivity with his home…
