Habitable Zone Less Habitable?

The hunt for exoplanets has been heating up for years, aided by new technologies and refined methods for finding smaller and smaller planets that may harbor life.

Integral to this hunt is the concept that the ideal planet’s orbit will be in a habitable zone that is far enough away from its parent star that water doesn’t completely evaporate and close enough for liquid water to exist.

In fact, a new earth-sized planet was recently found that was smack-dab in the middle of this Goldilocks zone and our current best candidate for an earth-like planet that could support life as we know it.

This zone however may not be as capacious as we once thought.
It looks like the heat from a star is not the only limiting factor for the survivability of liquid water. Tidal forces can also have a similar effect. This is called Tidal Heating.

The decline of a star’s gravitational pull on a planet means that some parts of a planet are tugged to a greater or a lesser degree than other parts. This not only deforms the shape a planet’s oceans but also its rocky interior (and even its atmosphere).

This constant kneeding of rock makes the planet hotter, potentially turning a wet world into a dessicated Venus-like planet. In fact, these worlds are being called Tidal Venuses.

Want Your Palm Read?

I know I am dating myself, but one of the most memorable lines from any of the hundreds of Bugs Bunny cartoons (which spans over 70 years worth of material) is, while dressed as a “swami”, he asks the antagonist character …

“Do you want your palm read?”

The brute holds out his hand and Bugs proceeds to paint his palm with red paint. Classic stuff for those of us old enough to remember such humor steeped in antiquity.  

As the cartoon world clearly knew back in 1949 that swami’s and palm reading and phrenology (reading “bumps” on the head) and other childish  notions were excellent vehicles to deliver humor, you would think that in modern times, the human race would continue to laugh off the fantasy of  anti-scientific newage such as divination by reading palms.  

Welcome to 21st century China, where ancient superstitions, antiquated habits, prejudices against people with certain blood types or certain last names, any many other forms of pseudoscience are alive and well. So what’s the latest news-making nonsense coming out of China these days?

That’s right … Palm Reading!

Reading the palms of children, to be more specific. According to this Reuters article, in a province in northern China, parents are paying 1200 yuan ($190US) to have their children’s palms read.  According to the reports, these readings can …

“determine the children’s innate intelligence and potential.”

Funny they should use the wording “innate intelligence”, which is the purported vitalistic component of chiropractic. One might dismiss it as a mere coincidence, but the notion that “innate intelligence” exists at all is a column which has been built exclusively for the Parthenon of Woo. Science has can not detect “innate intelligence”, and until someone comes up with a scientifically valid means of doing so, it does not exist.

It is also funny how the counterbalance in the article, a quote from a “pediatric expert”, offers the following retort:  

“This technology remains unaccounted for.”  

How weak. First, its not “technology” at all. It is a combination of mysticism and cold-reading. Second, it is not unaccounted for. Palm reading is well accounted for, and it simply doesn’t work. It is fortune telling. There is no evidence whatsoever for the validity of palm reading.

But this is China, and China is a big place with tons of people and ancient cultures and traditions that will never let go of their ingrained and cherished sacred cows. Take a look at this article for more on the wackiness of Chinese culture.

America and other countries around the world all have their own brands of cultural pseudoscience and woo, but the notion of palm reading strikes a chord of infantile thinking and humor steeped in ridiculousness the likes of which Bugs Bunny would still be proud of today.

 

 

 

The Search for a SuperSolid

The hunt is on for a new quantum state of matter called Supersolidity.

This state has never been conclusively observed but it would resemble another quantum state that has…superfluidity.

A superfluid is incredibly cool (barely above absolute zero in fact). It has zero viscosity which means it can actually climb up an out of a container. It can also flow through the tiniest pores of any container it’s in.

You may think that a supersolid would be super due to it’s incredible density but that’s not the case.

If you want more details. Checkout this article from my favorite science news-site Physorg.

Email Of The Year (So Far)

A recently received email reads, unedited, as such …

“I don’t like your attitude on the show. You said the Chem-trails are not real. I have seen them myself and have taken many pictures. I have also seen footage of a weatherman in Oregon saying that the military was doing experiments and laying the chem-trails. Why would you be so sure that they are not real. Who are you?? A bunch of snotty punks that never leave your office? I bet the whole show is there to make real people who seek real truth; look stupid. The “experts” like you claim to be, lie all the fucking time; and so do the people on your show. Thats why you dont have the guts to put up a phone number for calls. I bet you are funded by the goverment, or drug companies or something. No normal people are so arrogant. You are not the “experts” of anything, except lies.”

Wow, that’s quite an email.  Allow me to reply one sentence at a time.

iKnowledge

I love learning about new things, or learning even more about things I already know.  Sometimes I wish I could just get away for a week or two to a cabin in the woods and sit by a fireplace in a comfortable chair with a huge library of books and just read and learn 24/7.  There are many times throughout the year, especially around the beginning of new school semesters, that I go through my local colleges and universities’ part-time learning course lists and think about enrolling in one or two. But I have 2 jobs and live outseide of the city.  I always tell myself that I’ll take on a course or two one day when I have less things going on.

And then I discovered iTunes U.  What a great idea.  It’s basically a library of free courses in various formats (video, audio, eBook) offered from educators around the world.   From schools like Oxford, Harvard and Yale.

iTunes U has been around for a little while now, but they recently released the iTunes U iOS app.

The free iTunes U app gives students access to all the materials for your course in a single place. Right in the app, they can play video or audio lectures. Read books and view presentations. See a list of all the assignments for the course and check them off as they’re completed. And when you send a message or create a new assignment, students receive a push notification with the new information.

I’ve already started a list of courses I want to go through in iTunes U.  And they have lots to choose from.  Everything from iOS app creation to philosophy to history.   I just started Harvard University’s Justice with Michael Sandel.  I’m 3 “episodes” in and I’m really enjoying it and learning a lot.  There’s lots of cool science courses too and I’m going to go through one of those next.  And I’ve always been interested in American history.  So many to choose from.  My brain is a sponge and it’s ready to absorb knowledge.

I wonder if I could convince Steve to put up a course on skepticism and critical thinking on there.  Looks like we’ll have to grow him yet another clone. Or will we?….
