The project joined the most renowned scientist of the century with industry, military and thousands of ordinary Americans working at localities across the country to interpret original scientific discoveries into an entirely new kind of weapon, the Atomic Bomb.

Constitutional crisis is something which the government is unable to resolve and the constitution does not give any clarity regarding the issue. Colored vote constitutional crisis happened in 1955.
Explanation:
Colored vote constitutional crisis is also called the colored vote case. The Federal government decided to remove colored voters from the common voters list. This caused a conflict between the judiciary and other branches regarding the power of Parliament to alter the entrenched clause in the act mentioned in the constitution or veto that the constitutional amendment is not legal.
The crisis at last got a final conclusion when the government decided to enlarge the senate and modify the process of election of its representatives and amending the constitution by giving franchising rights to the colored voters.
