From the rough-and-tumble tables in biker taverns to the low-key games set up at family-friendly pizza joints, pool is a game accessible to just about anyone, regardless of skill level. For most amateur players, the most intimidating part of the game comes at the very beginning, when one player is required to break the rack, which begins with racking the balls well in the first place.
Racking the balls simply means placing them in the frame so that they are all touching each other. If the balls aren’t touching, they won’t break apart correctly, which can disadvantage the player who breaks. Breaking the rack sets up the beginning of the game, and if done correctly, can offer a significant advantage to the player who gets to break. Whenever breaking, always try to use the lightest stick available and make sure to chalk the tip well before you hit your shot.
The nuclear bomb simulator that lets users nuke their home cities.
NUKEMAP is an interactive map using Google Maps API and unclassified nuclear weapons effects data, created by Alex Wellerstein, a historian of science at the Stevens Institute of Technology who studies the history of nuclear weapons. The initial version was created in February 2012, with major upgrades in July 2013, which enables users to model the explosion of nuclear weapons (contemporary, historical, or of any given arbitrary yield) on virtually any terrain and at virtually any altitude of their choice. A variation of the script, NUKEMAP3D, features rough models of mushroom clouds in 3D, scaled to their appropriate sizes. NUKEMAP3D doesn’t work on most browsers anymore for NPAPI plugins are no longer supported by them.
The computer simulation of the effects of nuclear detonations has been described both as “stomach-churning” (by Wellerstein himself) and as “the most fun I’ve had with Google Maps since… well, possibly ever” despite the admittedly abjectly grim nature of the subject. Originally intended in part as a pedagogical device to illustrate the stark difference in scale between fission and fusion bombs, more than three million people as of 2012 have exploded some 30 million virtual nuclear warheads; having gone viral, the increased popularity of the website necessitated a move to new servers. The website averages five “nukes” per visitor. According to the site’s own counter, in November 2016 users had simulated over 90 million nuclear explosions.
The NUKEMAP was a finalist for the National Science Foundation’s Visualization Challenge in 2014.
Users can select the location and size of the bombs.
The site shows the spread of the mushroom cloud including casualty numbers.
