In April 1866, the U.S. Congress passed a law prohibiting currency notes to have a portrait or likeness of any living person, due to some members not agreeing with the five-cent note having the portrait of Spencer Clark.

Till now, U.S. law prohibits any portrait of likeness on its notes of people who are still alive, with even commemorative coins honoring past presidents being issued only after two years of the president's death.

It is not just woman's responsibility to

• Wash utensils

Out of these eight instruments, Bhaskara was fond of Phalak yantra, which he made with skill and efforts.

He argued that „ this yantra will be extremely useful to astronomers to calculate accurate time and understand many astronomical phenomena‟.

Interestingly, Bhaskara ii also talks about astronomical information by using an ordinary stick. One can use the stick and its shadow to find the time to fix geographical north, south, east, and west. One can find the latitude of a place by measuring the minimum length of the shadow on the equinoctial days or pointing the stick towards the North Pole
