New Blog Post Needle-in-the-Haystack-Politics
I am scared of people who accept zero crime in their world. In a large world with nearly 7 billion (7,000,000,000!) people, there will always be a few idiots... Yet, people exist who accept none. Typically, these people freak out at the sight of each incident which is reported in the media... even if it's on a different continent. A headline … more»
New Blog Post Recycled Headlines
The world's most precise clock We get this headline every six months or so. The experiment is cool, and drives down the precision to new levels, but I'll give the standard disclaimer: it's a frequency standard, not a clock. The logic clock is based on a single aluminum ion (electrically charged atom) trapped by electric fields and vibrati… more»
New Blog Post Snowmageddapocalypse 2010
Snowmageddon, aka the Snowpocalypse, has moved intothe recovery phase. I got about 2 feet of snow, but further north and in the hilly regions, they got more. 40" in some areas (i.e. more than a meter) My car. It's not a minivan. I earned my lesson from the snowstorm in December and parked on the opposite row of the lot. The way they p… more»
New Blog Post I Love the Internet
Thursday afternoon I had the realization that I still had not purchased a shovel; my inner drive to get one after our last big snowstorm waned immediately after I dug myself out and went home on vacation. So it wasn't until the latest storm was looming, along with the local ordinance requiring one to go to the store for a 24-pack of toilet paper, … more»
New Blog Post I Want to Spend Less Time with my Family
Corporation Says It Will Run for Congress With more than a twinge of irony, Murray Hill Incorporated, a liberal public relations firm, recently announced that it planned to run in the Republican primary in Maryland’s 8th Congressional District. Unfortunately they were founded in 2005, and you need to be 25 to run for the house. Related: A… more»

Go To New PostWhy does blood pressure decrease when you stand up from a lying down position?
Oh I agree, but that alone doesn't account for a change when standing up from a sitting upright position, because the relative heights of the head and heart don't change. Or is the idea that the increase in pressure to the lower extremities results in a corresponding decrease in the upper?

Go To New PostWhere Does Space End? It Must End Somewhere!
Laluskiie, Think about the balloon surface example. It is a toy 2D version. The real 3D picture is analogous but harder to imagine. Think about all existence concentrated on that 2D sphere surface. Only 2D creatures can live there. Flat amoebas with no thickness sliding around in the 2D...


Go To New Post2nd law of thermodynamics
I found a website (below) that discusses entropy. http://www.chiark.greenend. org.uk/~sbleas/creative/entropy/#11 Consider a box of small magnets. If the small magnets are lined up in the same direction, as a group they can attract other metal objects. If they are not lined up in the same...


Go To New PostHow big is the universe?
No, according to the projections I've seen. Our local group will stay together but gradually merge (on a very long timescale). So "our galaxy" will consist of both the present Milkyway and Andromeda and other stuff merged into a large elliptical (not so pretty as a spiral). Iggy is right, all...


Go To New PostCube- Square Law in Animals
How heavy do you think is the deadline that a natral animal can never lift things 1/2 time its own body weight however perfectly structured the animal is? Consecutive posts merged By the way, so the spiderman is thoroughly a mythological character but a science fictional character? As he can jump...
