Exponential ferret

Monday, March 21st, 2011

Last night a ferret just stood idly on the floor for about half a minute just staring blankly at us. It looked a bit like she was really concentrating, so the first hypothesis to explain this strange behavior was that she was trying to create a copy of herself through agamogenesis (asexual reproduction). This naturally led to the notion of a ferret able to replicate itself once every minute, and seeing that playing with exponential growth is always fun, this scenario deserves some illustrations:

0 minutes

one ferret.

1 minute

WOW!, did you see that? That ferret just duplicated!

3 minutes

Sweet, 8 ferrets. This is awesome.

5 minutes

Ehm, I love ferrets but 32 is a bit much.. how do you stop this thing?

18 minutes

Help! 268’000 ferrets just filled and breached the entire volume of our ~200 cubic meter apartment!

23 minutes

Neighborhood overrun, time to evacuate.

35 minutes

The blue dot is me, speeding away from the 50 square kilometer sea of ferrets half a meter deep.

48 minutes

Despite speeding like crazy I was just overtaken by a huge wave of ferrets, twice the area of Rhode Island and 30 meters tall.. By now there are 281 trillion ferrets in Norway.

1 hour

The 1 billion billion ferrets now cover all of Scandinavia with a height of the Eiffel tower

1 hour 15 minutes

Ferrets now rule the earth. covering the entire surface of the planet, filling up all the oceans, in a huge ferret sea 5 times the height of mount everest.
the 37 sextillion ferrets weight about 1/3 of the moon.

1 hour 23 minutes

The ferrets now have the same mass as the earth.

1 hour 55 minutes*

The ferrets now weigh 13’000 times more than our sun, the speed at which they can expand is limited, so the pressure and heat is extreme, this makes the huge ball of ferrets shine more powerful that any star, while a black hole has formed at the center.

2 hours 23 minutes

Ferrets now weigh the same as our entire galaxy, have formed a supermassive black hole and things are starting to get nasty.

3 hours

At 30 times the mass of the observable universe, outputting extreme amounts of energy through a geometrically challenged universe, the laws of physics are probably breaking down and fusing together again for the first time since the big bang.. It’s safe to say the ferrets have ruined reality as we know it.

 

Note: What happens after about 1 hour 30 minutes gets pretty speculative, it’s hard trying to apply the laws of physics to something that is physically impossible :)

Homeopathic sleeping pills

Monday, January 17th, 2011

A couple of hours back, I took 10 pills of the homeopathic sleeping “medicine” called Viasedal, markeded in Norway by Norges NaturmedisinSentral AS (Norwegian Nature medicine sentral inc).

Viasedal

these 10 oddly tasting little things constitutes a 500% dose of sleeping pills, yet I’m unsurprisingly very much awake, and will of course stay that way until midnight or so.

What is homeopathy?

To sum it up, homeopathy is the belief that what makes you sick, also makes you well. But only if you take it in ridiculously tiny doses.
Example: You’re having trouble sleeping, and since caffeine makes you NOT sleep, quite logically a tiny amount of caffeine will make you sleep.

The way you make homeopathic “medicine” is to mix 1 part caffeine with 99 parts water. Then you take out 1 part of this new mixture and put that in 99 parts of water, then that part into another 99 parts of water, and so on, and so on..

This is when homeopathy gets really fun, the more dilute (less of the active ingredient) you have, the stronger the “medicine” is.. Yes that totally makes sense. The strongest homeopathic medicine is actually so dilute that it crosses the a limit in chemistry known as Avogadro’s number, which means that not even a single molecule of the original substance is present in the concoction you are making. So you eventually end up with very expensive water.

The homeopaths say this makes perfect sense because water has magical properties unknown to science, and that “remembers” the stuff it was in contact with. The inventor (Samuel Hahnemann) called this a spirit-like healing force. Hopefully the water won’t remember all the fish poop and pollution it came into contact with while in the ocean.

Samuel "numbnuts" Hahnemann

Of course this is all bullshit, it’s completely asinine, defies even the smallest  amount of common sense, contradicts hundreds of years of research into chemistry and physics, and have been tested by science countless times, showing that taking homeopathic medicine does in no way differ from drinking water (pun intended).

Viasedal

The vial of Viasedal i got contained 50 pills, each weighing aproximately 0.35 grams.

pill weight

And the contents of this so called medicine is:

Viasedal Content

  • Calcarea phosphorica (or as normal people call it: Calcium phosphate, the stuff you get from milk).
  • Ignatia Amara (the plant Strychnos ignatia) Believed by homeopaths to help with Hysteria.
  • Arnica montana (wow, I’ve actually seen this plant outside lots of time without knowing it was magical)
  • Nux vomica (better know as the Strychnine tree, highly poisonous, at least if taken in non-homeopathic doses).
  • Jalapa (plant to help with colic and diarrhea) not sure what they’re supposed to do for sleep though.
  • Kalium carbonicum (or what scientists might call Potassium carbonate, or old school baking powder)

Now all of these are present in extremely small amounts, lets’ start with the calcium one. which says “D5″. in homeopathy this means 10% 5 times.

So in a 0.35 gram pill there should be 3.5 microgram of calcium. which is 0.003% of the daily recommended calcium intake.

The other ingredients are listed at 4C, this means 1% 4 times (in other words, 1% of 1% of 1% of 1% of X)

In other words, each pill should have 3.5 nanograms* (1 nanogram is one billionth of a gram) of the ingredients listed above.

To put that in perspective, if you ate 857* of these pills, the ingredients would in mass equal a single grain of sand.

The pill also consists of 0.000000005%* active ingredients (the ingredients above).

UPDATE:
*I finally got the amount of active ingredients in each pill from the supplier/producer:
Even though each pill weigh 0.35 gram, less than 0.035 grams is actually the diluted calcium “medicine”, the rest is just mostly inert pill material. So all numbers above are 10 times as high as they should, which means you would need 8570 of these pills to make up a grain of sand in active ingredients. each pill has 0.35 nanograms of the ingredient.

Why??

Why am I wasting my time eating “medicine” that obviously does not work?
Just trying to do my part, showing people that it does not work!

The belief in homeopathy actually kills people by preventing them from getting real medicine. Luckily homeopathy is not very wide spread in Norway, but some pharmacies like “Apotek Løven” at Byhaven in Trondheim promotes this crap

Apotek Løven

I’ll be eating the rest of my 40 pills on February 5th, as part of the 10:23 campaign, a UK based initiative (where Homeopathy is widely used). So along with thousands of other skeptical, scientifically minded people all over the world, I’ll be eating a bunch of placebo pills.

“Homeopathy, there’s nothing in it”

Carl Sagan day

Saturday, November 6th, 2010

Today (Just passed midnight, so here in Norway it’s Saturday 6th) is Carl Sagan day, the day each year where we celebrate the greatest human to ever walk this planet, Carl Sagan.

Carl Sagan

If I had to choose a favorite person of all of history, it would without any doubt be professor Sagan. A professor of astrophysics, and awesome scientist. He’s most known for being an important part of SETI and his PBS documentary Cosmos, which is a very good show and if you haven’t watched it, it’s definitely worth your time (note, the first episode might be a bit dull for some peoples taste, but it gets better from the second episode). Unfortunately I will be traveling to Spain Saturday, so will not be able to celebrate the day as much as I’d like.. But I will be watching my favorite episode of Cosmos, and maybe go out and have a glimpse at the stars if the weather permits.

A little taste of Cosmos, if you don’t watch it Zergs will rush your base and destroy all your barracks! (no seriously!)

Go Cern!

I’ve always been a big fan of particle physics and astronomy. So when CERN fired up their massive particle accelerator to 50% today (7 TeV PER PARTICLE! which is kinda sick), that was definitely a 9.98 out of 10 on the awesome scale :)

Hopefully some preliminary results can be released this summer :)

One thing that really surprised me was the funky graphics produced:

And the fact that they use VLC, the best video playback software ever made

The best joke ever

Tuesday, February 10th, 2009

I just read the best joke I’ve heard so far :D

Heisenberg went for a drive and got stopped by a traffic cop. The cop asked, “Do you know how fast you were going?” Heisenberg replied, “No, but I know where I am.”
