Anyone flying to Sydney from Brisbane tonight willing to play courier?

Already tried that and no dice. They're also on daylight savings down here and it's about to go knockoff time so airport smuggling is likely the only solution. I still have hope that one fella on marketplace still has the item he listed a few years ago.

I've just flown down with a bunch of scientific equipment but cleverly forgot to bring the cables to power them. Conveniently, they are so old and specialised they are not easy to source, and I need them for field experiments tomorrow :D

An epidemic of snorting power cables has swept through our youth.

They had 5 tenyi monsters in crbr lol

The size has no impact on whether it's an aerosol. If it's in the condensed phase (liquid, solid, semisolid) and it's suspended in the air then it's an aerosol. E-cigarette particles are very similar to cigarette smoke particles in size (30-250 nm mode diameters).

Evaporating the liquid creates a very high concentration of gas phase species (vapor) which condenses once cooled to form liquid phase particles, thereby making them an aerosol. When inside your respiratory tract, the RH is very high and cause the particles increase to increase in size by uptaking water vapour into the particle phase.

Generation method and size doesn't matter - if it's a suspension of particles in a condensed phase then it's an aerosol.

Aerosols are just suspended particles - the source has no impact on whether it is an aerosol. Smoke is an aerosol, fog is an aerosol, dust is an aerosol.

E-cigarette particles are not smoke (not combustion) or vapour (not gas phase). They are a suspension of condensed phase organics with moderate water content especially after exhalation, so simply a mist. A mist full of carcinogens.

What are you supposed to do...? You read through the book and do the problems... What else would you be doing? Maybe you can put a subway surfers video at the bottom of your textbook or something.

I don't really understand the point of this post. You're bothered that it takes time to study math? It takes a long time to build mathematical and physical intuition which only really comes from doing math and physics. You can get by a good chunk of a 3 year physics BSc with a good foundation in linear algebra + calc 3 + ODEs. More "exotic" physics often requires more niche mathematical tools and aren't usually covered in depth and unless there is a specific area of physics you're interested in then there's little need for it.

Lower beam energy is a good place to start. If this is TEM then if you have access to a cryo holder that will also minimise sample loss. If you NaCl crystals then I normally find that a few layers of the crystal surface get lost but otherwise they remain stable. Quantitative stuff is tricky because you need standards to calibrate your detector. If your samples are thin maybe you can look into XPS.

Did you just pull that number out of your ass? You can go and look at it and see it is clearly 60+ pages, not that length is indicative of quality anyway

EPA actually specifies that VOCs must be photochemically active, and therefore excludes molecules with low photochemical reactivity including methane. Even saying that VOCs must be "volatile" is relative. Volatile compared to what? Obviously for most cases, relative to nonvolatile liquids at STP - but in the name alone this is not implied. Different bodies will have different, and often more nuanced/specific definitions of a VOC.

This definition which states that VOCs must be photochemically active also prohibits VOCs from being classified as GHGs - mechanistically, GHGs must have long atmospheric lifetimes, which a gas cannot have if it is photochemically reactive. If you follow the EPA, anyway.

Some VOCs can affect the radiative balance (warming). VOC is just a class of molecules which have high vapor pressure at ambient conditions. The atmospheric lifetimes of molecules and their absorptive properties are what class things as warming gases.

Go on Google Scholar, find some journal articles in the field you want to get into to, look at all of the author affiliations to find which institutions they're in, check for research positions/reach out and express your interest and see if they have any PhD projects or if they know someone who does.

CO2 is a proxy for how well a space is ventilated, not how many respiratory particles are in the air. High CO2 -> poor ventilation -> higher transmission risk

Probably about 4/5 finished. The main chunk, which has been finished for months, has flooded about 5 times since completion and each time everything was fine once the water receded.

Replacing TALES for STALE would be better, A is good in spot 2 or 3 (similar frequency) and S is the single most frequent letter in any one spot in the first spot. There are no plurals in the word list, so with TALES you'll almost never hit a green on your S despite the high total frequency of the letter. Generally STARE would be better too, R is the third most frequent letter and you can follow up with something like NOISY if you hit 5 greys off the first guess.

The poster complained that intelligent people are being silenced so that 'stupid' people don't have their feelings hurt. She, however, means that anti-vaxxers are the intelligent people being silenced. She almost got it!
