Comment Wow We are Star Stuff (Score 1) 185

Looking at this macroscopically:

Stars kick out elements and supply enegy which creates compounds. Then life forms just as a method for reducing the enegy captured from the sun and stored in compounds back into lower energy things.

We are the entropic process in action.

Example:
Without us there would be massive amounts of stored enegy in the form of hydrocarbons. We are doing are part in the chain of things by releasing that back as thermal energy.

This even explains the evolution of intelligence as being more efficient at energy consumption.

I think this is specifically water based, or at least where things can be water like.
With water you get a scum boundary. Thermically there will be pressure to move the heat through the scum boundary. Which will generally be less thermally conductive. This will promote chemical processes that move the heat through the boundary.

The scum boundary becomes cell membranes and the chemical processes then become cellular mechnisims that seek their own energy input (feed on available chemically stored energy).

Comment How about applying copyright to corporations? (Score 5, Interesting) 263

It seems to me when politicians or corporations misuse a photo or song they get off with a "opps". Yet they want to throw people in jail.
Step #1 should be much steeper penalties to corporations and other functioning entities that should have proper procedures in place to avoid violations.

Comment If the ads win, I drop the site (Score 5, Insightful) 731

The people that are using ad-blockers are stating "I am annoyed by adds". These people seem to think it is a good idea to show the people that have flagged themselves as getting annoyed by ads more ads. That seems really really dumb.

These people should be careful what they wish for. There are many, many sites out there for people to browse on. Annoy a "customer" to much and it is very easy for them to go elsewhere.

Comment Education!! (Score 2) 312

There is a great difference between a mean value and an RMS value. Scientific people can work with the appropriate version so I don't see a problem with using the correct one for the correct occasion. And certainly science should stay with the correct term as appropriate.

What I believe the person is calling for here is the most appropriate use when communicating to the non-scientific person. This is an education issue in that the communication really should not use either term as a shorthand but should explain in full the effect of the distribution. Science uses mean and standard deviation (often also requiring a named distribution) because they are shorthands that describe the random behavior and have full meaning without any other explanation needed. So I say use neither term when communicating to the non-scientific as they do not fulfill the communication role to which they are intended.

What I believe should actually be done is proper education of all so that they understand the differences between various random distributions and move totally away from a "it is cold today, so global climate change based on heating must be a lie".

Comment last days of broadcast tv (Score 4, Interesting) 169

This is move is going to lose me as a viewer, not push me to subscribe to cable.

I have netflix. I get TV over the air. This sort of access was the only way for me to watch current shows other than at their prescribe transmission time. Other networks have made it "enter your cable bill number" to access this content as well.
I guess they don't want me, and those like me, to watch their shows at all.

I am certainly not going to subscribe to overpriced pile of crap that is basic cable. I grant you can get some good stuff by going specialty cable, but that is even more $$ on top of basic. I am almost never home at the right time to watch it "live" over the air. So count me and countless others like me off the viewship list. This is move is going to lose me as a viewer, not push me to subscribe to cable.

Bu-bye.

Concrete panels go in right behind the bore head. Infront of the maw is ground below the water table. The bore head forms a seal and the tunnel behind the bore head is pumped dry of water that leaks through.

Please exaplin "because all observable planets, besides earth, show the exact opposite happening" because as far as I can see Jupiter has one heck of a violent storm problem.

The center of the planet is molten. Space is cold. Air temperature is primarly affected by 1) solar input from ground heat and 2) radiative loss to space at altitude. More ground warming means more air rising, which means more cold air falling somewhere else. Making one spot hot is going to push more air up at that point, to balance that more cold air is going to "fall" somewhere else. One dynamic is that land cools quicker than water so we get arctic outflows. The world could get warmer and north america get colder due to all the cold air getting dumped on NA which is ideally shapped for north south air circulation.
