FDR

The day after Pearl Harbor was bombed, President Franklin D. Roosevelt appeared before a joint session of Congress and declared, “Yesterday, December 7, 1941–a date which will live in infamy–the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.” Roosevelt asked Congress to approve a resolution recognizing the state of war between the U.S. and Japan. Within an hour of the speech, Congress passed a declaration of war against Japan which officially brought the U.S. into World War II. 

Sublimation

Bypassing the liquid phase, sublimation is the process by which a solid transforms instantly into a gas. This happens when the forces of attraction between the particles in a solid are overcome, resulting in the particles breaking apart and forming a gas.

The process through which dry ice, or solid carbon dioxide, sublimes, is a typical illustration of sublimation. Dry ice is maintained at a temperature of -78.5 °C, which is significantly below its typical freezing point of -56.6 °C. The solid carbon dioxide particles have sufficient energy at this temperature to separate and become a gas directly, skipping the liquid phase.

The mechanism by which solid iodine sublimes is another illustration of sublimation. Iodine has a relatively low boiling point of 157.2 degrees Celsius, which means that it has sufficient energy to disintegrate and create a gas even at ambient temperature. As a result, the solid iodine may eventually vanish and emit a distinctive purple vapor.

Other solid materials, such as frozen water, naphthalene (mothballs), and certain kinds of chemicals, may also sublimate in addition to these examples.

 

Pennsylvania Postal Code

PA is the state of Pennsylvania's US postal abbreviation. To guarantee that mail is delivered to the right state, this abbreviation is often used when addressing envelopes. The postal abbreviations CA for California, NY for New York, and FL for Florida are some further instances.

Since the beginning of the American postal service, postal abbreviations have been used. The use of abbreviations allowed address labels to be smaller and simpler to see and write in the days when mail was often carried by horse-drawn carriages.

The first Postmaster General of the United States, Benjamin Franklin, advocated the idea of using postal abbreviations for the names of states in mail addressing in the 1790s, which is the first recorded usage of postal abbreviations in the country. These acronyms were derived from those that were often seen in British postal addresses at the period.

The list of postal abbreviations has altered and developed through time as additional states have been admitted to the Union and as postal regulations have been amended. Today, official postal abbreviations that are used to address mail are kept on file by the United States Postal Service (USPS). Periodically, these acronyms are updated to reflect any modifications or additions to the list of states and other geographic areas.

There are a variety of informal abbreviations that are used to address mail in addition to the official postal abbreviations. These abbreviations may be used by persons or organizations that choose to use their own abbreviations for postal addresses or by others who are not familiar with the official abbreviations.

 

Eagles Rock Band

 Linda Ronstadt is best known for a string of popular hits in the 1970s. She also assembled a band for her solo debut that ended up leaving to form the Eagles. Little did Linda Ronstadt know she was hatching Glenn Frey and Don Henley as the Eagles in the early 1970s when she hired them to play in her band and made them roommates while on tour. After touring together with Ronstadt in 1971, Frey and Henley formed the Eagles. It would be Glen Frey who gave the speech at Ronstadt's induction into the Rock and Roll Hall of Fame in 2014
