The real reason why Bill Gates is now the US’ biggest farmland owner

He’s going to chip the farmland, wait and see.

Here you go, the non sensational reasoning behind owning lots of land:
Late last year, Eric O’Keefe was researching a mysterious recent purchase of 14500 acres of prime Washington state farmland. His magazine, The Land Report, tracks major land transactions and produces an annual list of the 100 biggest US landowners.

Iya Iya.
Is that Trump in your picture profile, Roger? I don’t think I can take this post seriously for various reasons.

Light unbound: Data limits could vanish with new optical antennas
Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips.
Sub-diffraction optical writing enables data storage at the nanoscale
The total amount of data generated worldwide is expected to reach 175 zettabytes (1 ZB equals 1 billion terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the stack would be 23 times the distance to the moon. There is an urgent need to develop storage technologies that can accommodate this enormous amount of data.
Data Limits Could Vanish With New Optical Antennas and “Rings of Light”
New research throws wide open the amount of information that can be simultaneously transmitted by a single light source.

They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips.
The new work, reported in a paper published Thursday, February 252021, in the journal Nature Physics, throws wide open the amount of information that can be multiplexed, or simultaneously transmitted, by a coherent light source. A common example of multiplexing is the transmission of multiple telephone calls over a single wire, but there had been fundamental limits to the number of coherent twisted lightwaves that could be directly multiplexed.
How EVE Online and Borderlands 3 merge citizen science and gaming
If we can take just a fraction of the time that’s spent gaming, and make it useful for science, then that’s practically a limitless resource.
The idea of citizen science isn’t a new one. Amateur scientists have been making important discoveries as far back as Ug the Neolithic hunter and her ‘wheel’, while even Newton, Franklin, and Darwin were self-funded for part of their careers, and Herschel discovered Uranus while employed as a musician. It’s only from the late 20th century that it’s crystallised into what we know today, with the North American Butterfly Association using its members to count the popular winged insects since 1975. Zooniverse has users classify images to identify stellar wind bubbles, track coronal mass ejections, and determine the shape of galaxies. Then there’s Folding@Home and other cloud computing projects—they count too.
A speed limit also applies in the quantum world
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.
