I'm a Post-Doctoral Fellow in atmospheric remote sensing at the University of Toronto in Toronto, Ontario, Canada. I first came to Stack Exchange for practical reasons: Tex.SE has been of major help when I wrote my licentiate (midterm) thesis. Since then, I have discovered the joy of many websites. As my network profile will show, I'm interested in travel, outdoor, scientific skepticism, and as I work in academia, also in academia and LaTeX.

comment Why is the speed of light arbitrarily the limit?
@PhilPerry I believe ThomasAhle may be referring to the retracted "faster than light" neutrinos in Italy, that turned out to be due to a faulty cable.

comment How does heat actually stay kept in the carbon molecules in the atmosphere?
@DavePhD I suspect there is an XY problem here, though. It seems Akshat supposes that the Earth is heated by the presence of CO₂ because CO₂ "keeps" heat, whereas the real question may actually be a duplicate of "how do greenhouse gases trap heat".

comment If you were able to get rid of Hydrogen from a weather balloon as it were rising and expanding would the weather balloon rise further than usual?

Most burst long before they reach 50 km.

comment Adiabatic expansion in the atmosphere
Gases are very inefficient heat conductors.

comment Effect of CO2 on the environment, besides greenhouse effect and ocean acidification
This is a good question for the new Earth Science stack exchange, that should hopefully reach public beta soon.

comment If I drop a leaf twice from the height of a tree in a completely controlled environment, will the trajectory in each case be the same?
This question is really about chaos theory, not about quantum mechanics. A leaf falling is not about quantum mechanics.

comment Being in a solid state, why is ice slippery?
It's not slippery if it gets cold enough.

comment Being in a solid state, why is ice slippery?
@jwenting True. There are many other models that my observation would support. The water ice in the outer solar system is hard as rock...

comment Being in a solid state, why is ice slippery?
From personal experience, ice is not (very) slippery at -40°C, but worst near 0°C. That supports the water layer idea.

comment How far we can see in the thickest possible fog?
The densest fog I've seen probably had visibility of some 10 meter, but in whiteouts people can get lost in their garden.

comment How far we can see in the thickest possible fog?
Does a whiteout (snow) count? And you're mentioning water fog, but ice fog can be much denser.

comment Why does ice form on bridges even if the temperature is above freezing?
@AJMansfield But that's not the bridge having a conductive heat sink, that's the bridge lacking a conductive heat source. In other words, the road is heated from below, but the bridge isn't. But the bridge does not lose heat through conduction (it is, to a first order, only in contact with air, and air is a bad heat conductor).

comment Why does ice form on bridges even if the temperature is above freezing?
Heat loss via conduction won't cause bridges to cool down faster than the surrounding land. I think the radiative effect is dominant.
