A person’s Erdős–Bacon number is the sum of one’s Erdős number—which measures the “collaborative distance” in authoring mathematical papers between that person and Hungarian mathematician Paul Erdős—and one’s Bacon number—which represents the number of links, through roles in films, by which the individual is separated from American actor Kevin Bacon. The lower the number, the closer a person is to Erdős and Bacon, and this reflects a small world phenomenon in academia and entertainment.

The idea of Erdős–Bacon numbers has been written about by Simon Singh in the British media[1][2] and Benjamin Rosenbaum,[3] among others,[4] in the blogosphere. Roles as self, as a cameo appearance, or as an extra are often included for the Bacon component. The Erdős criterion technically refers to collaboration on mathematical papers, but it is often relaxed to include general research articles for the Erdős–Bacon number.[5]

In general, to have a defined Erdős–Bacon number, it is necessary (but not sufficient) for one to have both appeared in a film and co-authored an academic paper.

Notable scientists with defined Erdős–Bacon numbers include popular astronomer Carl Sagan. One of the best-known actors with a number is Natalie Portman, whose authorship of a psychology paper while at Harvard University earned her an Erdős–Bacon number of 6.ős–Bacon_number


The Waffle House Index is an informalmetric used by the Federal Emergency Management Agency (FEMA) to determine the impact of a storm and the likely scale of assistance required for disaster recovery. The measure is based on the reputation of the Waffle House restaurant chain for staying open during extreme weather and for reopening quickly, albeit sometimes with a limited menu, after very severe weather events such as tornados orhurricanes. The term was coined by FEMA Administrator Craig Fugate in May 2011, following the Joplin tornado; the two Waffle House restaurants in Joplin remained open after the EF5 multiple-vortex tornado struck the city on May 22.[1][2] According to Fugate, “If you get there and the Waffle House is closed? That’s really bad. That’s where you go to work.”

The Index has three levels, based on the extent of operations and service at the restaurant following a storm:

  • Green: the restaurant is serving a full menu, indicating the restaurant has power and damage is limited.
  • Yellow: the restaurant is serving a limited menu, indicating there may be no power or only power from a generator or food supplies may be low.
  • Red: the restaurant is closed, indicating severe damage.

Bath Iron Works (BIW) is a major American shipyard located on the Kennebec River in Bath, Maine, United States. Since its founding in 1884 (as Bath Iron Works, Limited), BIW has built private, commercial and military vessels, most of which have been ordered by the United States Navy. The shipyard has built and sometimes designed battleships, frigates, cruisers and destroyers, including the Arleigh Burke class, which are currently among the world’s most advanced surface warships.

Since 1995, Bath Iron Works has been a subsidiary of General Dynamics, the fifth-largest defense contractor in the world (as of 2008). During World War II, ships built at BIW were considered by sailors and Navy officials to be of superior toughness, giving rise to the phrase“Bath-built is best-built.”


Samuel Dewey Byrd (October 15, 1906 – May 11, 1981) was an American professional baseball player and professional golfer. He went by both “Sammy” and “Sam”.

Byrd was born in Bremen, Georgia but grew up in Birmingham, Alabama. He played Major League Baseball from 1929 to 1936 for the New York Yankees and Cincinnati Reds. Byrd’s nickname was “Babe Ruth’s Legs”, a reference to the fact that he often would appear as a pinch runner at the end of games toward the latter part of Ruth’s career.

In 1936, Byrd quit baseball to pursue a career in professional golf. He won six events on the PGA Tour between 1942 and 1946. He lost the final of the 1945 PGA Championship to Byron Nelson, 4&3, in match play.

Byrd is also the only person to have played in a World Series and competed in golf’s Masters Tournament. He made one appearance in the1932 World Series (game 4) while playing for the New York Yankees – as a defensive replacement for Babe Ruth – in the bottom of the 9th inning. He finished twice in the top 10 at the Masters: third in 1941 and fourth in 1942. During his last appearance in 1948 he tallied the highest score ever at the second hole recording a 10. He finished the round with a 12-over-par 84.

Byrd was inducted into the Alabama Sports Hall of Fame in 1974. He died in Mesa, Arizona in 1981 at the age of 74.

In Australia and New Zealand, the “Freshman 15” is sometimes referred to as First Year FattiesFresher spread, or Fresher Five, the latter referring to a five-kilogram gain.

Despite how commonly the Freshman 15 is asserted, an Ohio State University study showed that the average college student gains only two to three pounds in their first year. Additionally, it showed that college students did not gain any more weight than non-college students of the same age, and that the only factor that did increase weight gain was heavy drinking.


There is at least one Anthony Melchiorri Look Alike contest somewhere out there.

The Bay of Fundy is known for its high tidal range. The quest for world tidal dominance has led to a rivalry between the Minas Basin in the Bay of Fundy and the Leaf Basin in Ungava Bay, over which body of water lays claim to the highest tides in the world, with supporters in each region claiming the record.

The Canadian Hydrographic Service finally declared it a statistical tie, with measurements of a 16.8 metre (55.1 feet) tidal range in Leaf Basin for Ungava Bay and 17 meters (55.8 feet) at Burntcoat Head for the Bay of Fundy.[6] The highest water level ever recorded in the Bay of Fundy system occurred at the head of the Minas Basin on the night of October 4–5, 1869 during a tropical cyclone named the “Saxby Gale”. The water level of 21.6 meters (70.9 feet) resulted from the combination of high winds, abnormally low atmospheric pressure, and a spring tide.

Leaf Basin has only been measured in recent years, whereas the Fundy system has been measured for many decades. The tide at Leaf Basin is higher on average than tides at Minas Basin; however, the highest recorded tidal ranges ever measured are at Burntcoat Head and result from spring tides measured at the peak of the tidal cycle every 18 years.
