A Structure for Deoxyribose Nucleic Acid Updated +Created
Starting line:
We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A,). This structure has novel features which are of considerable biological interest.
The Eighth Day of Creation explains the "salt" part as that was the usual way to prepare DNA for X-ray crystallography, where something binds with the phosphate groups of DNA
The paper then shoots down other previously devised helical structures, notably some containing 3 strands or phosphate on the inside.
Then they briefly describe the structure.

NP-hard cryptosystem Updated +Created
This is natural question because both integer factorization and discrete logarithm are the basis for the most popular public-key cryptography systems as of 2020 (RSA and Diffie-Hellman key exchange respectively), and both are NP-intermediate. Why not use something more provenly hard?
MacArthur Fellows Program Updated +Created
Holy fuck what a eye watering amount, $800k over 5 years as of 2025, this is exactly what Ciro Santilli would need to push forward OurBigBook! He also fits the requirements quite well, as a "creative person". For Americans or US residents only though, sad. Outdated requirement given the Internet age.

Alpha School Updated +Created
The school's model is to offer two hours of academic learning each day using "AI tutors", while the rest of the day is dedicated to developing life skills
The founding lady has several other interesting schools e.g. gt.school:
We believe that kids do not need 12 years to finish school — they can accomplish so much more when given the environment and resources to do so
At GT School we’ve revolutionized the classroom by replacing traditional teachers with dedicated guides who serve as mentors
Pretty awesome.
