BLAST (biotechnology), Basic Local Alignment Search Tool, an algorithm used in bioinformatics; Blast cell or precursor cell, in cytology, a type of partially differentiated, usually unipotent cell; Blast disease, a disease of cereal crops; Blast injury, a complex type of physical trauma resulting from direct or indirect exposure to an explosion
The following blast are blown on Rosh Hashanah: Tekiah (תקיעה) is a single long blast of the shofar. [4] Shevarim (שברים) is composed of three connected short sounds. [4] Teruah (תרועה) - in most Sephardic and Ashkenazi traditions, this is a string of many short-lived, broken blasts made by the tongue (e.g. tut-tut-tut-tut, etc ...
The blast was felt as far away as Princeton, New Jersey (50 miles or 80 kilometres). [3] It sent a geyser of water 250 feet (76 m) in the air. [ 4 ] The blast has been described as "the largest planned explosion before testing began for the atomic bomb", [ 4 ] although the detonation at the Battle of Messines in 1917 was larger.
In the first instance, in Exodus 19, the blast of a shofar emanating from the thick cloud on Mount Sinai makes the Israelites tremble in awe. The shofar was used to announce the new moon [4] and the Jubilee year. [5] The first day of Tishrei (now known as Rosh Hashana) is termed a "memorial of blowing", [6] or "day of blowing", [7] the shofar.
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
A blast wave reflecting from a surface and forming a mach stem. The air burst is usually 100 to 1,000 m (330 to 3,280 ft) above the hypocenter to allow the shockwave of the fission or fusion driven explosion to bounce off the ground and back into itself, combining two wave fronts and creating a shockwave that is more forceful than the one resulting from a detonation at ground level.

The range for blast effects increases with the explosive yield of the weapon and also depends on the burst altitude. Contrary to what might be expected from geometry, the blast range is not maximal for surface or low altitude blasts but increases with altitude up to an "optimum burst altitude" and then decreases rapidly for higher altitudes.
