Help with your bike
A section of Bengaluru’s cycling community is volunteering to deliver medicines and other essentials for the elders and other vulnerable groups.
Relief Riders, headed by Bengaluru’s bicycle mayor Sathya Sankaran, will be of service from 6 am to 10 am every day. The group was formed during the first wave of the pandemic. With the city in the midst of a two-week lockdown, the cyclists have returned to volunteer again.
“We are close to 200 volunteers in Bangalore 20 in Hubli-Dharwad. There are few other cities who have shown interest as well,” says Sathya. “The disease is now believed to be airborne. So, we are extra careful this time. There are a few guidelines one has to agree before signing up to be a volunteer.”

In 1967, one of the world’s oldest particle accelerators, built in the 1930s, was sent from the University of Rochester, USA to be housed at Panjab University, Chandigarh. Invented by American nuclear scientist Ernest O. Lawrence in 1929–1930 at the University of California, Berkeley, this particular type of particle accelerator, also known as a cyclotron, is an apparatus in which charged atomic and subatomic particles are accelerated by an alternating electric field while following an outward spiral or circular path in a magnetic field. Cyclotrons are built on the same principles as more famous particle accelerators, such as the Large Hadron Collider at the European Organization for Nuclear Research (CERN), but on a smaller scale, used not only for conducting experiments in nuclear physics but also f
