BrainTruffle:  Fluid dynamics feels natural once you start with quantum mechanics at


You need to use real measurements, on real systems, to match your different simulation strategies to real things. You are guessing by eyeball. You can get massive amounts of data from a number of places, or your own experiments. A billion particles “good” simulation pales compared to an Avagadro’s number of real particles. The instruments set the bounds on the observations and what you need for the simulations. Share your raw data, your simulation code, the raw results from the simulation, the raw data on the matching. Case studies of small regions. Do like CASP Protein Structure Prediction Center and get many groups to write and test their own algorithms on new challenges. Most of the “quantum” groups on the Internet are not sharing their measurements, algorithms and results on the Internet in ways that allow comparisons “at scale”. So, from my point of view, looking at all human knowledge on the Internet, they are are playing at Science Technology Engineering Mathematics Computing Finance Governance Other (STEMCFGO), not really serious. Good global scale collaboration compares things, it records everything, it share in lossless globally accessible formats. It uses a few well supported lossless completely accessible formats. It use SI units (The Internet Foundation has more because SI does not cover all that is being done).

Any video of particle simulations is using a compressed lossy video format. You have to separately share the raw lossless data, or you are just showing eye candy. Check. Take some full resolution data (with intensities like from star fields), convert them to YouTube video then compare raw to the video pixels. Almost none of the pixel (voxel) values will be the same. It is just eye candy. NASA does it, ESA does it. Shame on them. Some of the groups made a bit of effort, but it needs global collaboration, open lossless auditable accessible methods.

“Feelings” are like “eye candy”. They might feel good, but they are not science. If you want to cause excitement, you actually have to do the real thing and measure what generates “feelings” in real humans.
