A 200 year old physics experiment could help build future computers The intersection of old and new ideas often yields significant breakthroughs.
Researchers at Nanyang Technological University in Singapore have harnessed a 200 year old optical effect called the Poisson spot to create complex light structures known as optical skyrmions.
To generate these exotic patterns, the researchers used a laser and a tiny circular disc, producing stable swirling patterns in light without relying on expensive materials.
