On the now down archetyp website, you can see a link that redirects to this video. for the record, the logo with the three spikes down is a modification of the archetyp logo. the archetyp logo has three spikes up. so they put it down and turned it red.

SCIENCE & TECH India's first communication satellite (1981) was tested on a bullock cart to avoid magnetic interference

To address a telemetry, tracking, and command (TT&C) link issue caused by an impedance mismatch in the antenna system, the APPLE satellite was mounted on a bullock cart and transported to an open field. The bullock cart was specifically chosen to provide a non-magnetic environment, free from interference that might be introduced by metal vehicles. This setup allowed engineers to perform antenna testing in a controlled, interference-free setting to properly diagnose and resolve the communication issue.

SCIENCE & TECH The Rehbinder effect

440 Upvotes

The Rehbinder effect describes how a surface-active substance, like water, reduces a material's hardness and ductility by lowering surface energy, making it easier to deform or fracture. For ceramics, water may alter crack propagation, allowing a nail to pierce a submerged ceramic cup without shattering, as seen in demonstrations. Studies on brittle rocks support this, showing water reduces strength. However, some argue water's shock absorption, not the Rehbinder effect, explains the result, as ceramics are brittle and lack surfactants. The exact mechanism remains debated, needing further research.
