Drinking heavy water

[Wanderfound]

@blahblahblah

our conscious perception of positive qualities (in this case, ‘sweetness’) as relative to more abstract qualities of the subject (‘heavy water’). our perceptions are our perceptions, but there are physical realities that our bodies and the outside world both depend on. [/quote]

The usual psych jargon for differentiating between “subjective sensory experience” and “external reality being perceived” is to call the first one “qualia”.

@blahblahblah

in as generally as i can think, it can be said that heavy water has greater structure / less entropy than regular H2O.

Not sure that you’re right on that, but I’ll leave it for a math/physics type to sort out.

@blahblahblah

since time and space are recognized as being the same (thanks physics!),

Related manifestations of an underlying thing, but not “the same”.

@blahblahblah

we can say that mass/structure is a greater distance (time or space) from the origin of the universe (‘the big bang’)

Not sure what you’re trying to say there.

@blahblahblah

i see a similar dynamic in drugs that cross the blood-brain barrier. the relatively sudden increased mass of the central nervous system is a pleasurable experience

Not really, no. It ain’t mass that drives pharmaceutical qualia; it’s the interaction of drug molecules with neuroreceptor systems, usually by closely mimicking the physical shape and polarity of endogenous neurotransmitters.

[quote=“blahblahblah, post:47, topic:91652, full:true”]simple sugar would seem to buck the trend, but then i start thinking about about tesselation and how space is filled. giving your body lots of little carbohydrates makes it easy to fit them all in you, again allowing for greater density intake. like packing a car full of basketballs vs golf balls. the golf balls leave less empty space.

Molecular shape does matter for biology. The major reason for the difference in biological impact of saturated vs unsaturated fats is that the straight-line structure of saturated fats allows them to pack more densely than the crooked structures found in unsaturated fats.

I have a friend who has a license to work with Tritium. There is a lot of cost and paper work evidently.

Did he… did he say he’s saving his urine to get the heavy water back…?

Whether drinking heavy water will kill you or not is a topic often discussed among scientists who do neutron scattering. Also deuterium is a useful replacement for hydrogen in water and other molecules for neutron scattering because it has a very different scattering cross section.

“The Heavy Water War” was a good netflix series about the same deal.

You can’t taste nuclei. Any taste is either contaminant or imaginary.

Although you can smell them. Deuterated musk compounds smell ‘burnt’ in comparison to their hydrogenated equivalents. There’s apparently also a noticeable difference between the smell of sulphur-32 and sulphur-34 compounds

Wow. I just looked this up, read through the comments, and said to myself “Wow. Y’all some nerds.”

Now, who wants to come visit me in my glass house and check out this super cool trebuchet I’ve just built? Because it can throw the hell outta some stones.

Too late. I have already been categorised as jackass, and I believe the union of the sets is empty, because a nerd is knowledgeable about something, whereas a jackass is knowledgeable about nothing.
