Jupiter's core is a fuzzy core, not a solid core. It has a bizarre magnetic field and the NASA probe that was there or near there in 2017 confirmed that it has a core (as opposed to the theory that it has no core at all). But it's not solid (as was another possible scientific hypothesis). The discovery by the Juno spacecraft was ultimately an unexpected one and the spacecraft was able to help scientists dismiss or debunk several theories regarding the planet. Large regions of Jupiter are non-convective. And in addition, Saturn may have a fuzzy core too.

Just summarizing what I got from the video.

The Australian National University (ANU) operates a quantum random number generator (QRNG) that produces true random numbers by measuring quantum fluctuations of vacuum[^1]. The system generates random bits at 5.7 Gbits/s and makes them freely available through both a web interface and API[^5].

Unlike traditional pseudorandom number generators that rely on mathematical algorithms and seeds, ANU's QRNG creates genuine randomness by detecting quantum phenomena - specifically the electromagnetic field fluctuations that occur in a vacuum due to zero-point energy[^1].

The service offers multiple ways to access the random numbers:

• Direct web interface for visualization and downloads
• JSON API for programmatic access
• Pre-generated random number files up to 5GB in size
• Integration libraries for various programming languages including Python, R, Java, and .NET[^5]

The QRNG has practical applications in:

• Generating cryptographic keys
• Randomized clinical trials
• Computer game simulations
• Password generation
• Weather prediction modeling[^5]

The technical implementation is documented in peer-reviewed physics journals, with the quantum random number generation process detailed in Applied Physics Letters and Physical Review Applied[^1].

So, if an academic paper is published in an open journal by an average citizen with an obsession for learning from online sources. So, there are no credentials but a decent work history. A prestigious college downloads the paper. What are the possible reasons?

More children have long covid than asthma. Reinfection can increase risks.
