Have you ever read a book where a fantastical event occurs and thought, "Wait, that can't really happen…can it?" I'm going to go ahead an assume you answered yes. Did you ever then actually stop and give it some thought to figure out if the event described was at all physically possible? I'm going to go out on a limb and guess most of you answered no.
You know who didn't answer no? Masters physics students at the University of Leicester. Under the tutelage of Professor Mervyn Roy, these students write, edit, review, and publish The Journal of Physics Special Topics. The goal of the journal is to teach the students not only about the process of academic publishing, but also how to think critically. For example, one of the papers published recently was entitled, "James' Giant Peach Transport Across the Atlantic". In it, students researched the feasibility of whether or not 501 seagulls could lift a giant peach and fly it across part of the Atlantic ocean. Spoiler alert: they can't.
While that may seem like a downer to some, I love the fact that these students are sharpening their inquiry skills in such an imaginative way. Check out other papers from last fall's edition on topics such as Breaking Bad, War of the Worlds, James Bond, and my personal favorite "Walking on Sunshine" by Katrina and the Waves.
And now for your weekly dose of geek:
- You keep using that weight, but I do not think it means what you think it means.
- 13 space missions to watch out for in 2013. Special shout out to Orbital Sciences at #4 where I worked in a former life.
- Not only do other stars have their own planets, they likely have their own comets too.
- Swedish indie rock group, Shout Out Louds, release their latest single as a record made entirely out of ICE. You have see and listen to this to believe it. [VIDEO]
- British designers come up with a household light for the developing world powered only by gravity.
- Wonderful interview with David Attenborough. #longread
- 5 superhero organisms: metazoa that can absorb DNA of others, snails that turns flesh into metal, mind controlling barnacles, shapeshifting octopuses, and fungi that eat radiation. Someone call Hollywood, STAT.
- Giant squid caught on video in the Pacific Ocean south of Japan. It's almost the length of a school bus, with eyes the size of dinner plates. One step closer to the Kraken!
- You've heard of jumping beans? Get a load of these jumping genes, which also have the awesome nickname of Space Invaders.
- The color of your beverage container affects your perceived taste of its contents.
Lastly, I leave you with this:
Parasitic wasp stalks roaches, stings them, injects their brains with neurotransmitters, steers them to her lair, and lays egg. Resulting larva then burrows inside STILL LIVING roach and feeds on its insides.
May you never be reincarnated as a roach. @Summer_Ash





Were those African, or European
swallowsseagulls?doesn't matter... they could still grip it by the
huskstemHow big is Giant? and why am I now craving for a nice juicy peach. Any size ;)
I always wondered that about James and the Giant Peach. You know, Roald Dahl was a latent genius, so I wouldn't put it past him.
But since we are on geeky topics, let me put something out to THIS community specifically.
Do you ever wonder if we have some of THESE people [below, Astroturfing Internet Shills] here wandering among US?!
(rhetorical question, because other than flagging trolls-- and these people are trained not to "troll" per se, so they wouldn't be easily identifiable). The thought gives me pause because there was a time (was it about a year ago? About the time when Steve Benen took over MaddowBlog and brought a lot of new and unfamiliar faces into this community with him) when the Maddowfan poster/Troll ratio sort of exploded.
I know all these Benen enthusiasts trailed over with him, but maybe he brought his own set of trolls too. OR maybe some astroturfers used the opportunity to target this site and this forum.
Take a look at this article (before it gets taken down):
I Was a Paid Internet Shill: How Shadowy Groups Manipulate Internet Opinion and Debate
Some interesting quotes from it (and more links below, in case this one goes dead) (bold emphasis is mine):
Here's some other links:
Guardian: Astroturfing: what is it and why does it matter?
Alternet: Corporate-Funded Online 'Astroturfing' Is More Advanced and More Automated Than You Might Think
SmartPlanet: Online astroturfing gets sophisticated
Are peaches Migratory?
Regarding internet shills, I found the article interesting in that the purported shill writing the article went from apolitical on Israel to a supporter of Israel after promoting pro-Israel positions for 6 months.
Pharmaceutical companies have used a similar tactic to get doctors to promote their drugs. They hire doctors as "thought leaders" to give presentations to fellow doctors. The marketing target is the thought leader and not the other doctors.
http://ethicalnag.org/2010/10/31/is-your-doctor-a-thought-leader/
I wonder if these shill operations are sophisticated enough that they are targeting the shills and not the community the shills think they are targeting.
Drat! Joel beat me to it.
Lots of parasitic wasps out there, but I didn't know there was one that could lead its victim to their own tomb! Not real sure if that's cool or creepy...
To a "die-hard" fan of AMC's The Walking Dead, the whole concept of the roach being truely "walking dead" is so poetic. It only makes me crave the return of the 3rd mid-season break of that amazing show.
BTW...
The parasitic wasp described here was the basis for Alien...
Those wasps are the most perfect metaphor in nature for understanding how the private equity business works.
As much as we are all repulsed by the sight, or even thought of a Cockroach, this story about the Parasitic, Jewel Wasp, is pretty much the 2nd best new thing, in the World, today, in the waning hours of this weekend--right behind the Baltimore Ravens beating Denver, last night, when everyone thought it was a done deal for the Broncos, in not 1, but 2 over-times, with 31 seconds left in the 1st over-time, by kicking a field goal and ending the 2nd over-time before it could even get going good. Thanks Rachel, you've topped off my weekend!
Since a gram is the mass of one cubic centimeter of water at 4 degrees Centigrade why do we not store 1,000cc of water at 4 degrees centigrade in every lab worldwide?
But if you don't know the EXACT weight if a Kg ( and therefore everything that relays on the Kg), how can you be sure that your 1g of water at 4c is really 1g?
Only way to be sure is to get an atom of known atomic weight do a bit of maths to find out how many atoms of that element = 1Kg and use nano-tech to construct a perfect sphere/cube using the precise number of atoms.
Construct a new one every few years and compare against the others to see if their is any change in density/weight/size etc...etc...
The DEFINITION of a gram is the MASS of one cubic centimeter of water at 4 degrees Centigrade. That is how they constructed the La Grande kilogram in the first place. The La Grande is convenient (used to be convenient?) since it does not need a refrigerator or a vessel to carry it in but if there is a problem with the standard kilogram any competent lab can pour 1,000cc of 4 degree water into one container and have an identical one to place objects in and make them balance to reproduce a 1kg weight as often as necessary. After that you can count the water molecules in the 1,000cc and set the standard kilogram as the number of water molecules in 1,000cc of distilled water.
cool!
The "household light powered by gravity" creates the possibility of providing power to third world villages that currently must use fire in order for their residents to read after dark. Now THAT is world-changing and worthy of our support!
It's rather unscientific to say that the light is powered by gravity.
The light is actually powered by human muscles, which must first provide potential energy to the system by lifting the bag of rocks. Then gravity converts the potential energy into kinetic energy in the form of electrical energy, powering the light or whatever else you plug into it.
The principle isn't much different from those radios that work from electricity generated from a wound-up spring. Or from a battery that is charged up a bit by the user first turning a crank. The power comes from human muscles. Which comes from chemical energy that we obtain from our food. Which comes from... you get the idea.
I don't really mean to nitpick, but these distinctions are important if we ever hope to educate the electorate sufficiently that they will stop voting for politicians who believe that evolution and earth science are "lies from the pit of Hell."
Thanks, Summer! I followed the link about the color of a beverage container out to a story about glowing Civil War soldiers as well!
The author of XKCD (excellent geeky web comic if you never read it) recently added a 'What if?' page to the XKCD website. Basically the same premise as the James and the Giant Peach thing. Readers submit weird science questions and he answers them in awesome and detailed narrative.
http://what-if.xkcd.com/
Both xkcd and What if? are excellent!
Sorry writer, but they could carry a giant peach, it depends on how big the peach is. We did this with pigeons and it works.......please deposit 25 cents and try again.
Intel demonstrated a wireless power supply may eliminate all the laptop cords entirely.
The patent on this technology expired almost 100 years ago. Most of Tesla's patent artwork was confiscated upon his death.
Nikolai Tesla was the original developer.
This site shows the concept of operation (the tower still stands in NY).
Here is a YouTube video that makes fun of the whole concept.
This type of power was banned by international treaty because of radio interference.

Your Week in Geek always fascinates me. I'm now teaching 6-12 grade Honors classes and these Physics Special Topics are perfect for them. Thank you for sharing these fantastic(al) sites!
This week, internet activist geek Aaron Swartz takes his own life after his wealth is bled dry defending against a disproportionate federal case against him. (Article) (Blog entry by lessig)
my husband and i really enjoy your show, i would like to comment on two things that really bother us and hope that maybe someone of the powers that be, (government) might be listening to you for me, first on school safety, why not put national guardsmen at each school, they are trained and armed soldiers doing what they do best, protecting us and our children, second on the social security issue, the holiday for decreased social security taxes is over, but rather than making people pay more now, the simple answer is to remove the caps althogether, lots of people get social security or s.s.i., who have never worked a day in their lives, so must make it a fair tax with caps at all, thank you for listening, i do believe these problems can be easier solved!!!
It really is amazing what fungi can do. We take it for granted, but fungi is all around us. Ever seen that whiteish-grayish powdering looking stuff that's stuck to the skin of a dark grape? That's yeast! It's a fungi. With enough grapes, and a blender, and a few chemicals and materials for processing, you can make your own vino!
Really, all you really need is juice, sugar, and yeast. It's amazing what those little fungi's can do. They eat the sugar and they poop out alcohol. They also poop out carbon dioxide.
When I started making my own vino (for home consumption, never for sale), I thought, "what other fruits would make for a great wine?"
Well, I can tell you that honeydew and watermelon makes for a LOUSY wine. But blueberries, blackberries and most especially raspberries make for an amazing wine. The smell (or bouquet) of raspberry wine is like that of roses! It is heavenly!
And you can't buy it in the store. At least I've never found a store that sell it. But it is so worth making!
A mass is not a weight.
In college, I had an astronomy prof who gave us a similar exercise. She had worked on a crappy old TV movie, "Fire in the Sky", starring Richard Crenna. She was the scientific advisor, but apparently they didn't listen to her very much, so she got her revenge by having her students pick that piece of doody apart to find all the scientific inaccuracies, (and boy, it was chock full of them). It was a great way to engage us in a task. By the way, our final exam was to design an unmanned mission to Pluto, detailing the instruments you'd take, why, and what you expected to find with each. Good times!
re: James and the Giant Peach. Sometimes animation is just animation. The inability to suspend disbelief in favor of imagination could be at the bottom of our country's cultural descent into crap culture.
