Happy Pi Day from all of us at the Bartlett Public Library! We celebrate today as Pi day since the 
date, March 14th, is the same as the first three digits of π (3.14).
You can learn more about the mathematical concept of Pi in Why Pi? by Johnny Ball, in our juvenile nonfiction section at j530.8 BALL.
You can celebrate Pi Day with challenges from NASA scientists and engineers as part of their Pi Day Challenge! Good luck!
On August 21st, there will be a total solar eclipse for parts of the United States. NASA reports:
Anyone within the path of totality can see one of nature’s most awe inspiring sights – a total solar eclipse. This path, where the moon will completely cover the sun and the sun’s tenuous atmosphere – the corona – can be seen, will stretch from Salem, Oregon to Charleston, South Carolina. Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun’s disk. (https://eclipse2017.nasa.gov/)
You can use the link below to check out NASA’s interactive website. You can use the website to determine what time the eclipse will be visible from where you live.

Remember to wear special protective glasses when you observe the eclipse!

On May 18th in 1980 Mount St. Helens erupted in Washington. This eruption caused a huge avalanche, and ash from the eruption fell as far away as Minnesota.
Throughout April, scientists watched a bulge on the north side of Mount St. Helens grow larger and larger. Finally, on May 18 at 8:32 a.m., a sudden 5.1-magnitude earthquake and eruption rocked the mountain. The north side of the peak rippled and blasted out ash at 650 miles per hour. A cloud of ash, rocks, gas and glacial ice roared down the side of the mountain at 100 mph. Fourteen miles of the Toutle River were buried up to 150 feet deep in the debris. Magma, at 1,300 degrees Fahrenheit, flowed for miles. (http://www.history.com/this-day-in-history/mount-st-helens-erupts)
On this day, May 14th, in 1973 the unmanned Skylab 1, America’s first space station, was launched from the Kennedy Space Center. Immediately there were problems with the launch as a meteor ripped off one of the solar panels and part of the shield. The next Skylab mission would be launched on May 25th with crew members who were trained to make the workshop safe for them to work in.

Today we recommend: Secrets of a Civil War Submarine: Solving the Mysteries of the H. L. Hunley by Sally M. Walker.When the Union blockade of all ports in the South stopped supplies from reaching the Confederate Army, Horace L. Hunley decided to create a submarine that would be able to sneak up on enemy ships and blow them up. After many years of trial and error, the H. L. Hunley actually succeeded in sinking the USS Housatonic in February of 1864. But the submarine never returned to port, and her crew perished in the Charleston Harbor. This book presents the history of the Civil War submarine the H.L. Hunley, including the construction, mysterious sinking, recovery, and restoration.
This book was the 2006 winner for the Robert F. Sibert Informational Book Medal. This book hooked me right from the start, and the numerous pictures, sketches, and maps made it easy to picture the submarine. This book is perfect for those interested in the Civil War or archaelogy. It is a great nonfiction book packed with information that avoids being dry or dull. You can find it in the Juvenile Nonfiction section at j973.757 WALKER or as an audiobook in the Juvenile Audiobook section j973.757 WAL.
