Sagan’s “Cosmos” Getting a Sequel…on FOX?!?

August 11, 2011 Leave a comment

In some very interesting news, the classic PBS documentary ‘Cosmos‘ starring Carl Sagan will be getting a sequel in 2013.

It will star Neil deGrasse Tyson, whom you may recognize from the PBS show NOVA scienceNOW!

The new Cosmos show will be produced by ‘Family Guy’ creator Seth McFarlane, who is well known to be frustrated with the scientific literacy of the United States, or lack thereof.

What is especially interesting about this is that the special will be aired on FOX, which has never been known to support scientific literacy of its audience. Fox News in particular comes to mind…

Anyway I hope this actually goes through and we get to see it. It probably won’t top the old-school charm of the original ‘Cosmos’, but should be great nonetheless.

 

 

 

 

Does TV Watching Make You Sick? Not Exactly…

I’m a little annoyed with some headlines hitting a few news websites today:

TV Watching Raises Risk of Health problems, dying young

Excess TV time linked to early death

TV time tied to death, diabetes risk

The stories are talking about a study getting published this week in the Journal of the American Medical Association

The study is a meta-analysis of 8 studies over the past 40 years which look at the correlation between watching television and risk of diabetes and cardiovascular disease.

The study found, unsurprisingly, that increased television watching was correlated with an increased risk of type 2 diabetes and heart disease.

The pooled relative risks per 2 hours of TV viewing per day were 1.20 (95% CI, 1.14-1.27) for type 2 diabetes, 1.15 (95% CI, 1.06-1.23) for fatal or nonfatal cardiovascular disease, and 1.13 (95% CI, 1.07-1.18) for all-cause mortality.

In layman’s terms, this means that for each 2 hours of television watched per day, risk of type 2 diabetes increased by about 20%, risk of developing fatal or non-fatal heart disease increased by about 15%, and risk of dying of any cause increased by about 13%.

So does watching TV make you sick? Not exactly.

I’m not doubting the results of the study, though they should be taken with the usual grain of salt that should be taken with all epidemiological studies.

They are observational studies, not controlled studies in a lab. There are many variables which can influence the results.

That being said, the results of the study are not surprising and I have every confidence that there is truth in there.

But the media takes these types of studies, gives them a sensationalized headline and doesn’t put them in the proper context.

Watching TV does not make you sick; being lazy makes you sick. What this study is really showing is that watching TV correlates to a lazy lifestyle.

There’s nothing wrong with kicking back and watching some Star Trek reruns or even *groan* Dancing with the Stars. Just make sure you go out for a jog now and then. Or play some basketball. Or just do anything that isn’t sitting around and being lazy!

I’m sure snacking is a big factor in the results of this study as well. No doubt increased time in front of the TV leads to eating more unhealthy foods.

But if you sit in front of the tube and eat baby carrots or oatmeal, then you are probably not at a huge risk of developing heart disease or diabetes.

So if you watch a lot of TV, you’re not necessarily going to die young because TV doesn’t make you sick.

But if you eat a lot of junk food and don’t exercise, then you might die young. But then again, THAT’S not exactly news, is it?

“If Undergrads Are Our Future, We’re All Doomed!”

I love the comics strip “Piled Higher and Deeper”

It depicts the trials and tribulations of being a graduate student. Even though I ditched the life of a grad student after my masters, I can still remember the horrors I experienced. And now, A MOVIE!

Is this “squee” worthy? I think so… SQUEEEEEEE!

 

Shock wave from a Trombone Caught on Film

May 29, 2011 Leave a comment

The weak shock wave emanating from a trombone was captured on film and presented at the 161st Meeting of the Acoustical Society for America in Seattle.

The researchers used schlieren photography to capture the images. This method is able to image fluids through the changes in their refractive index and is used largely in aeronautical engineering to study air flow around airplanes.

It’s also wicked-cool :)

So Its The End of the World…

As you are no doubt aware, tomorrow is the rapture.

Yes, Jesus is going to return to Earth tomorrow to take all the good people with him to heaven. This has been predicted by a multi-millionaire radio station owner named Harold Camping.

How did he make this prediction? I’ve actually seen a couple derivations from Camping on this, but an excerpt from FamilyRadio.com states:

Holy God reminds us that one day is as 1,000 years. Therefore, with the correct understanding that the seven days referred to in Genesis 7:4 can be understood as 7,000 years, we learn that when God told Noah there were seven days to escape worldwide destruction, He was also telling the world there would be exactly 7,000 years (one day is as 1,000 years) to escape the wrath of God that would come when He destroys the world on Judgment Day.

Seven thousand years after 4990 B.C. (the year of the Flood) is the year 2011 A.D. (our calendar).

4990 + 2011 – 1 = 7,000

Amazingly, May 21, 2011 is the 17th day of the 2nd month of the Biblical calendar of our day. Remember, the flood waters also began on the 17th day of the 2nd month, in the year 4990 B.C.

God is proving to us that we have very accurately learned from the Holy Bible God’s time-plan for the end of the world.

So there you have it, irrefutable proof that the world is ending tomorrow.

Sorry :(

So what will become of the sinners? Well we are going to be left behind to think about what we did…until October.

On October 21st, the world will actually be destroyed by fire.

Now, at first I thought that I might be able to escape judgment. I mean, I’m not a bad guy. I donate to charity, I’ve helped old ladies cross the street, and I’ve never murdered anyone.

But then I realized how horrible a person I really was. I eat meat on Fridays. I don’t go to Church every Sunday, and I’ve been spending the past 5 years living in sin with the love of my life.

Not only that, but I believe that homosexuals should be allowed to get married! What was I thinking?!? Camping has clearly pointed out that it is the gays who are to blame for this horrible upcoming Judgement.

Camping says God will punish America and the rest of the world for Gay Pride and same-sex marriages, just as Sodom and Gomorrah were punished with fire and brimstone in the Old Testament.

I should have known better.

So now the only question is: What am I going to do with my last night on Earth before Jesus metaphorically (or perhaps literally) bitch-slaps me?

A good question. I should probably get drunk. But then, it is May 2-4 long weekend, so that was probably going to happen anyway (for my non-Canadian readers, May 2-4 is the colloquial term for Victoria Day, a national holiday in Canada).

I could repent, but that somehow feels like giving up.

I could sell all my possessions and spend it all on strippers and drugs. But then, I might catch a nasty disease and have to spend my last few months on Earth suffering more than I should.

Well I guess I will be getting drunk. If I wake up tomorrow before Jesus arrives, I will blog again. Otherwise, this may be the last time you hear from me. Thanks for being such loyal readers!

How will you all be celebrating Judgment Day?

Sloooow Going

Posts have been slowing down a little as of late. This is due to a number of factors including my training for a 10 km run (6.21371192 miles for my American readers) which I completed in 1 hour and 2 minutes! I was hoping to get in under an hour, but considering a year ago I could barely run 2 km, this was a pretty big accomplishment for me!

Hurray for strengthening your cardiovascular system!

Posts have also slowed down because I’m actually get to do some physics-related stuff at work. We are developing a new toy for inspecting pipes and I get to look at data and read about Faraday’s law and play with magnets!

While completely fake, this explanation is still better than Insane Clown Posse's explanation of magnets working by "miracle"

But I could never forget about you guys. I still love reading and writing about science and that will never change, so I’ll be back to full form in no time.

But in the meantime, here’s 31 bad (and therefore, awesome) jokes for nerds. Enjoy!

Land Mine Detection With Stuff That Smells Good

At the March meeting of the American Physical Society, an abstract was presented entitled “Detection of Nitro aromatics via fluorescence quenching of pegylated and siloxanated 4, 8-dimethylcoumarins”.

The BBC reported that this study utilized curcumin, which is found in the spice turmeric and is one of the key ingredients in many curry powders.

Now, I wasn’t at the meeting so I may be wrong, but the abstract does not describe using curcumin, but coumarins. Coumarin is also a fragrant chemical compound, but it is not found in turmeric. It is actually used as a rodenticide and was banned as a food additive in the United States in 1954.

If I’m lucky enough to have a reader who knows more about this work, or was at the conference and saw this talk, I would very much appreciate a clarification. In any case, the research is still pretty interesting.

The abstract described the work of a team of researchers at the University of Massachusetts Lowell. The group reported their research into using optical sensors to detect chemical explosives, such as those found in land mines.

Optical sensors work by reacting the molecules released into the air of the chemical explosive. The optical properties of the sensor material changes after interacting with the explosive. Measuring these changes in optical properties is called fluorescence spectroscopy.

The group created co-polymers and tested their use in fluorescence quenching, which means that when you shine a light on these polymers in the presence of explosives such as trinitrotoluene (TNT), the light given off by them would dim.

The BBC also reports that

The team, which is funded in part by the US government, is already in discussions with a company to develop the technique into a portable detector device.

which, given the huge problem of land mines in war-torn countries, could turn out to be very useful.
