According to the Lawn Tennis Association, only 15,000 British players picked up a padel racket in 2019 but by the end of 2024, that figure was more than 400,000. Of those, about 399,000 are probably mispronouncing it: think pah-dell rather than paddle.
We were not expecting to find so much richness and depth from a physics point of view underneath the sole of a shoe, says Adel Djellouli, a scientist at Harvard University and co-lead of the study. In a new study, scientists explore the physics that give rise to the familiar squeak of basketball shoes sliding on a hard surface.
Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.
Squeaking occurs across various contexts including shoes, bike brakes, rubber tires, and biomedical implants when soft and hard surfaces contact each other. Researchers used high-speed photography to study a rubber block sliding across hard acrylic to identify the source of these sounds. The investigation revealed that pulses similar to earthquake dynamics drive the squeaking phenomenon.
On a cool Wednesday afternoon before the US Open last year, Daniil Medvedev and Alexander Zverev were busy fine-tuning their games in an intense practice set at Louis Armstrong Stadium. Danielle Collins and Christian Harrison, semi-finalists in the mixed doubles tournament, were scheduled to take their place at the hour and the American pair duly arrived a couple of minutes before their allotted slot.
The increase is being largely driven by the Gen Z population, as basketball is now the 6th most popular sport among the 18-24 year old demographic. Despite there being major continental competitions across Europe like the EuroLeague and EuroCup, basketball is a sleeping giant that is awakening in the UK. This movement is likely to cause a massive shift in the sport's associated betting markets as well, but the big question of whether basketball can break into the mainstream remains.
INDIANAPOLIS -- All-Star forward Kevin Durant will not play for the Houston Rockets on Monday night after spraining his left ankle when he stepped on a fan's foot during a recent game. Coach Ime Udoka provided the update about 90 minutes before his team was scheduled to play at the Indiana Pacers, saying Durant "tweaked" the ankle. He provided no timetable for a return.
