  • NATIONAL HUG A PLUMBER DAY – April 25

    NATIONAL HUG A PLUMBER DAY

    National Hug A Plumber Day on April 25th recognizes those who come to our rescue when pipes leak or drains are clogged. 

    Plumbers have kept the water flowing since ancient Rome. Whether it is a minor leak to a major clog, a plumber will have the right tool for the job. They also help us install the right pipes and plumbing types when building a house or new business. They’re the water specialists – designing plumbing systems that work when we need it. Thanks to plumbers, we have hot water on demand. Showers come with a variety of options and kitchens provide the ultimate convenience. 

    If you consider the contribution of plumbing to human life, the other sciences fade into insignificance. ~ James P. Gorman

    Consider how plumbers improve our lives and health in the modern world. Their contributions could be inventions the human race would have a difficult time living without. Given a choice between using only a flush toilet or a smartphone for the rest of your life, which would you choose?

    Progress is electricity, school consolidation, church remodeling, second farm tractors,
    second farm cars, hay balers, corn-pickers, grain combines, field choppers and indoor plumbing. ~ Ollie from the film Hoosiers

    From the moment you wake in the morning to every glass, flush and wash, a plumber makes life easier even if you never have to call one.

  • NATIONAL DNA DAY – April 25

    NATIONAL DNA DAY

    On April 25th, people across the nation recognize National DNA Day. On this day in 1953, James Watson and Francis Crick formally announced their discovery of deoxyribonucleic acid (DNA) in a short letter published in the science journal, Nature

    Fast forward to 1990, when scientists from around the world came together to begin mapping the human genome. Known as The Human Genome Project, approximately 2000 scientists in six countries set to work mapping the nucleotides in human DNA. In the process, the project learned that humans share genes with other species. Some of the species the project mapped included yeast, mice, and the fruit fly – all species commonly studied in science already.

    Quote markThe genome is our map of life. ~ President William Clinton

    On June 26, 2000, the first draft of the human genome was released. By April of 2003, the project released 92% of the mapped human genome. The Telomere-to-Telomere (T2T) Consortium took on the challenge of sequencing the final 8% of the human genome. On March 31, 2022, they published six letters detailing the completion of the final 8% in the journal Science.

    The mapping of the human genome has transformed medicine and research. The ENCODE (Encyclopedia of DNA Elements) Project launched soon after the human genome was sequenced to study further and catalog data related to the human genome. Research including the study of different cancers and more advanced diagnostic tests may change medicine forever.

  • NATIONAL ZUCCHINI BREAD DAY – April 25

    NATIONAL ZUCCHINI BREAD DAY – April 25

    NATIONAL ZUCCHINI BREAD DAY

    Each year on April 25th each year, National Zucchini Bread Day encourages bakers to make this delicious bread.   

    Many explorers who came to the Americas brought back what they considered strange foods, including the zucchini. The zucchini eventually found its way to Italy, where it was named zucchino. Native Americans referred to zucchini as “something eaten raw.” However, we all know that zucchini tastes best cooked, especially in bread.

    Zucchini bread is similar to other quick breads like banana bread. Other quick breads you might be familiar with making include muffins, scones, and biscuits. When baked, Zucchini and banana bread go into the oven in loaf pans. When finished, slice and serve with butter, peanut butter, jam, or just plain. 

    Basic Ingredients of a Quick Bread 
    • Fat – Bakers use shortening, butter, margarine, or vegetable oils depending on the texture they wish to achieve. Follow recipes and use only the fat called for to achieve the desired results. 
    • Sugar – Granular sugar, brown sugar, and some sugar substitutes are used. Many bakers add fruit for sweetness, substituting a portion of the sugar in the recipe. 
    • Eggs – As an emulsifier and a binding ingredient, eggs add volume and texture to quick bread
    • Flour – Most bakers use all-purpose flour, but other recipes will use alternative flours. Always follow the recipe because other ingredients have been adjusted to improve texture when using an alternative flour.
    • Liquid – Usually, milk or water moisten the mixture, activate the gluten in the flour, and dissolve the sugar.
    • Leavening agent – Either baking powder or baking soda + an acid (such as cream of tartar) are used. Baking powder is baking soda with the acid already added.
    • Flavoring ingredient – Bakers incorporate a variety of spices, fruits, vegetables, nuts, and extracts. Each one complements the flavor of the main ingredient. In a quick bread, bakers often use vanilla to enhance the flavor. 

    When mixing your ingredients, be sure to follow the recipe instructions. Over mixing prevents the bread from rising while baking causing the bread to be dense.

  • NATIONAL EAST MEETS WEST DAY – April 25

    NATIONAL EAST MEETS WEST DAY

    National East Meets West Day on April 25th commemorates the day the Eastern Front of the Allied forces met the Western front on the River Elbe. Also known as Elbe Day, this day marked an important step toward ending World War II. 

    World War II had been raging for over six years. During the previous year, several events had begun turning the tides of the war against the Axis powers. In April of 1945, the Allies were marching toward peace. However, it would require a coordinated effort from both American troops in the East and Soviet armies from the West.

    The commanders directed their units not to make contact with each other. Their orders were to remain on their eastern and western banks of the river while officers from each division formalized occupation of Berlin.

  • NATIONAL TELEPHONE DAY – April 25

    NATIONAL TELEPHONE DAY

    On April 25th, we observe National Telephone Day. Around the world, there are 9.82 billion mobile phones. And while some predicted the landline to be obsolete by 2020, there are still about 931 million landlines around the world.

    Obtaining a Patent

    The correct answer to a trivia question like “Who invented the telephone?” is the name on the patent. In this case, the whole world knows the answer is Alexander Graham Bell. Had his attorney been delayed by foul weather or poor planning, the answer may be a different name.

    On February 14, 1876, Marcellus Bailey, one of Bell’s attorneys, rushed into the U.S. Patent office in Boston to file the patent for what would be the telephone.

    Later the same day, Elisha Gray filed a patent caveat for a similar device. A caveat is an intent to file for a patent.

    There was also a third contender. Antonio Meucci filed a caveat in November of 1871 for a talking telegraph but failed to renew the caveat due to hardships.

    Because Bell submitted his record first, the patent office awarded Bell the patent on March 7, 1876. Gray contested this decision in court, but without success.

    Alexander Graham Bell

    Born March 3, 1847, in Edinburgh, United Kingdom, Bell taught at a boys’ boarding school. The sounds of speech were an integral part of his life. His father developed a “Visible Speech” system for deaf students to communicate. Bell would later become a friend and benefactor of Helen Keller.

    Three days after the patent was approved, Bell spoke the first words by telephone to his assistant. “Mr. Watson, come here! I want to see you!”

    By May, Bell and his team stood prepared for a public demonstration. And there would be no better place than the grand stage of the World’s Fair in Philadelphia. On May 10, 1876, in a crowded Machinery Hall, a man’s voice transmitted from a small horn and carried out through a speaker to the audience.

    One year later, the White House installed its first phone. The telephone revolution began.

    Bell Telephone Company was founded on July 9, 1877, and they installed the first public telephone lines from Boston to Sommerville, Massachusetts, the same year.  By the end of the decade, nearly 50,000 phones existed in the United States.  In May of 1967, phone companies across the country installed the 100 millionth telephone line.

    HOW TO OBSERVE #NationalTelephoneDay

    • Celebrate by calling someone and telling them Happy National Telephone Day!  
    • Share your vintage telephone pictures on social media.
    • Try making a call with a rotary phone.
    • #NationalTelephoneDay to show the different phones that have been used!

    Educators, visit the National Day Calendar® Classroom for lessons designed around National Telephone Day.

    NATIONAL TELEPHONE DAY HISTORY

    In May of 1967, the 100 millionth telephone line was installed in the United States. On May 11th, governors and dignitaries for U.S. territories joined President Lyndon Johnson on the largest conference call ever held up to that date. Each governor, dignitary, and the President were issued gold phones to commemorate the day. At the same time, a proclamation was issued declaring May 12th as National Telephone Day.

    There is no record of the day being observed again on that date. However, National Day Calendar continues to research the origins of this technology day. 

    Telephone FAQ

    Q. Do payphones still exist?
    A. Yes. However, the number of payphones began declining in the mid-1990s. If you’re looking for a payphone, some cities and states have payphone maps. You can also look in public places like federal offices, libraries, transportation hubs, large shopping centers, and gas stations.

    Q. When was the first mobile phone invented?
    A. Motorola made the first mobile phone called the DynaTAC 8000x in 1983.

    Q. When was the first smartphone invented?
    A. The Simon Personal Comminicator was released in 1994 by IBM.

     

  • NATIONAL LIBRARY WORKERS DAY – Tuesday of National Library Week.

    NATIONAL LIBRARY WORKERS DAY

    Each year in April, National Library Workers Day recognizes the valuable contributions library staff make every day to their communities through their hard work and dedication. The observance takes place annually on the Tuesday of National Library Week.  

    Libraries do so much more than house the books we borrow nearly any time of the day or night. (Yes, any time, day or night. Online reservation is highly popular.) Today as always, library workers are masters of research. They find the obscure quote (or partial misquote as the case may be) helping you to annotate your research paper correctly. When you’re on a job search, they offer internet access and computers so you can polish up your résumé, too.

    Libraries also archive local history. The names of pioneers and settlers are usually recorded in books and newspapers of the era. Many libraries across the country house those books, papers, and many other resources.

    Library workers champion our youth. They foster creativity and are a wealth of diverse opportunities for growth. Not only do they create projects and inspiration for our youth, but they also create them with enthusiasm! It can be quite infectious. 

    Despite all libraries and their employees provide to their communities, their budgets and salaries continue to shrink. This day brings awareness to this continuing trend. Libraries and their employees continuously utilize the latest technologies to make information, books, and resources more accessible. Their knowledge and ability bring valuable tools directly to communities that might otherwise go without. They also serve every age group, many organizations, and entire communities.

    HOW TO OBSERVE #NationalLibraryWorkersDay

    • Give a shout-out to a library worker you know.
    • Discover all of the resources your library offers.
    • Support your library and its staff.
    • When budget time comes for your city or state, do your part to support your library.
    • Visit your local library.
    • Use #NationalLibraryWorkersDay to post on social media.

    NATIONAL LIBRARY WORKERS DAY HISTORY

    The American Library Association sponsors National Library Workers Day, and it was first celebrated in 2004. It was started as a way to raise support for better benefits and salaries at a time when they had been stagnant for years. The observance continues to promote increased benefits and wages for the services provided by library workers every day.

    Library Workers FAQ

    Q. What kinds of jobs do library workers do?
    A. Depending on the size of a library, there are a variety of jobs to be done. Some library workers are assistants to the librarian while others manage the entire library. A library may also hire an archivist, technician or media specialist. Others may work specifically with youth, developing programs for the children’s area.

    Q. Do libraries offer internships?
    A. Yes. Many libraries offer internships to those interested in library sciences. It’s a terrific way to develop the tools to be a skilled librarian.
