Comment Other reason for not finding ET signals (Score 1) 312

What if we are the first? The first civilization because our planet and solar system is fairly old as compared to many other place in the galaxy.

Maybe we need to broadcast radio waves, in a grand gesture that some unknown culture in the future will hear us. Am I worried about bug eyed monsters invading us, because we are transmitting a "We are here signal."? - No.

Comment Location, location, location! (Score 1) 389

Standard sized buildings and prices vary widely from location to location.
A few years ago the median house price in Detroit was $9600 - that's median, mind you.

Some spots in California on the cost - houses average 1.5-2 million for 1200 sqft starter homes...

According to the US Dept Commerce - the average new home price was $238k and the median price was about $282k

Comment logical conclusion (Score 5, Informative) 148

Interesting argument, but it relies on a logical fallacy that implies our wealth is derived from being free, and not from being a growing industrialized nation. China might be an argument against your supposition.

  Other thought - while our country was "free" there were horrors, like rivers catching on fire from accumulated waste, and working situations like "the Jungle" by Upton Sinclair.

Our wealth is beng polarized by the new Oil Barrons, and wasteful wars, etc.

Comment Sports cars have 2 seats = bad definition (Score 1) 143

Just some examples I can think of 4 seater sports cars - which few people will argue are not sports cars:
Porsche 911 (all models except for the GT3 which has no back seats)
BMW M3 and M5
Nissan GT-R
Aston Martin Rapide and DB9

Yes there are more, but you get the point. Some will argue that a true sports car must be a 2 seater, and be a convertable, but.... so what.

Comment FAT ASTRONAUTS!!! (Score 2) 228

Human body fat is the most efficient way for a human to store energy. Give them enough (recycled) water, some vitamins and protein and they will shed weight all the way to Mars, and back maybe too.

Cryo sleep will not work, because joints will become fibrosed, muscles will atrophy, etc.

So to figure out how FAT our ASTRONAUTS will be - we'll need to look at some numbers.
A pound of fat can expend about 3500 KCAL of energy.
An average male basal metabolic rate is around 2000 KCAL/day.

Now using conventional fuel - the trip takes 214 days, using a constant propulsion nuclear motor might shorten it to 120 days

Soooo - ballpark FAT ESTIMATES are for conventional fuel 214 x 2000 = 428,000 KCALs
428,000 KCAL /3500KCal/fat = 122 pounds (or about 56 Kilos extra)

    Nuke fuel require them to only gain about 70 pounds extra.

Now this is a one way trip - so lets double the weight to provide for our FAT ASTRONAUTS to get back home safely

So now we are looking at 244 pounds EXTRA - or a 444 pound (200 KILO) Buzz Aldrin... for conventional fuel
and for constant acceleration nuke powered craft - a 340 pound Buzz Aldrin

This will make the newer movie version of the RIGHT STUFF a bit different to watch. All those neck beards out there - yep - you're training for a MARS mission....

Comment End of life expectations (Score 2) 646

I think the general public needs to know that pretty much every patient having chest compression that I've seen being brought into the ER have been dead. That's roughly 0/100. Now if it happens in front of you, a MD, now that's a different story - maybe 30-40% go on and live their lives.

Movies portray CPR, resuscitation, end of life, defibrlllation (the heart "jump start" paddles), etc, in a wholly unrealistic way, and I think it's wrong to continually mislead the public. They have no idea about breaking multiple ribs on the persons chest, electric burns from the defibrillator, brain damage from hypoxia, etc

There may be differences between the above mentioned methods of CPR, but I bet they are trivial, and even more so for the general public.

I'm an oncology surgeon still taking trauma call, and I've seen more than my fair share of death. There are many things we can do to prolong life, but until you, or a loved one gets to that point, then it's hard to say what you will do, and how much you will panic at losing a loved one.

Comment Re:I wonder (Score 1) 433

It's been illegal for many years now, for MDs to accept ANY form of gratuity from drug reps, and the vast majority of MDs out there have never, ever, received any sort of payback from any drug company.

The only interaction now is basically being a guest at a lecture, where you have to listen to another MD give a talk on some subject, with no product names being mentioned, and get to eat a piece of rubber chicken..
