People will not always agree with those in control of their paycheck. It happens all the time.  There are then two choices: Adapt and make the best of it, or quit.  First always give your professional opinion, but through the regular channels, or your efforts might backfire.

Science and Astronomy Questions

I am slightly skeptic. There might be a few if's involved in this experiment, like if they actually achieved the claimed pressure, if they didn't see something happening to the diamonds instead, and so on, but who knows.  There is a race to do this first, which means getting things published gets m...

Planets with potentially breathable atmospheres

Emulated, yes, replicated, perhaps too hard.  The machines that we build work so differently.

Planets with potentially breathable atmospheres

At 37°C water has a vapour of 6.3 kPa, so that would be a reasonable pressure limit for humans.  That corresponds to 18-19000 m altitude on Earth.  At that altitude the blood inside the body would still have higher pressure, so there is no risk of the blood boiling, but spit, tears and moisture in t...

The maths:  Venus' angular size was 28" (0.008°) and its altitude 22°.  An airplane altitude of 11 km seen at a 22° angle gives a distance of 29 km.  The wingspan of a 747-400 is 64m, or 0.126° at 29 km.  The fuselage width is 6.5m or 0.013°.  So the airplane could have covered Venus completely.

I noticed an airplane at cruising altitude headed towards Venus on the evening sky today, and said to my kids, "look, it's going to cross Venus".  And sure enough, Venus blinked.  It didn't get fully obscured, but there was no doubt.  That would have been an awesome photo if I had had a te...

Science and Astronomy Videos

We invent the logic, and discover the consequences of that logic. True, but not necessarily in that order, which leads to the philosophical questions.  We knew how to add natural numbers before we invented the logic behind it (like the Peano axioms).  In many cases I would say that it's the discove...

Planets with potentially breathable atmospheres

If you have more than about 500ppm of C02, the atmosphere will be disorienting to breathe even if you have enough oxygen. Any more than 1000ppm, and you're dead within a few hours. I've measured CO2 in my house for a decade, and over the past month it looks like this: x.png The diurnal cycle mostly...

Remember way back when I said that forecast skill will improve not so much by improving our knowledge of the physics but by raising the computer power and grid resolution? Yes, but just throwing more computer power at the problem will never take you as far as you can go.  You also need to be clever...

I'm getting more and more impressed with the short term forecasts by the Norwegian met office considering Norway's difficult terrain.  The forecasts have improved significantly over the past few years.  I occasionally check the quality for my location.  The grid size for short term forecasts have be...

Quotes about Universe for loading window

I like insights dating from the antiquity, though not always derived correctly.  For instance, Lucretius (1st century BC, paraphrasing 4th century BC Epicurus who believed in an infinite universe and many earths):"It cannot by any means be thought likely that this is the only round earth and sk...

I think the video was intended to be funny more than to be accurate. :) I was invited to follow the Philae landing from the office of the Norwegian Space Centre and took an early day off for this event.  The "touchdown" moment was a bit unclear.  As I recall it, there was a confirmation th...
