The Mysterious Messenger is a rich middle grade urban fantasy debut starring young psychic Maria de la Cruz, by the award-winning artist Gilbert Ford. Eleven-year-old Maria de la Cruz is trapped under the thumb of Madame Destine, her pseudo-psychic mother. Destine is a bona fide con artist who will stop at nothing to swindle her customers into believing she can communicate with the dead. But Maria, unlike her mother, has a big secret—she really can communicate with the dead, most frequently with a ghost named Edward who has been her only friend since she was a child. It’s not long before this clairvoyant young sleuth gets wrapped up in an epic journey that combines bookish mystery with the literary movement of the Beat poets and art and jazz history. Maria may have the power to unlock extraordinary secrets, but can she find the treasure Edward sends her clues about? More importantly, can she find true friendship? This smart, big-hearted debut novel is perfect for fans of Book Scavenger, Winterhouse, and The Vanderbeekers of 141st Street. Christy Ottaviano Books

Provides facts about the chocolate chip cookie inventor, and imagines what could have led her to develop the Toll House cookie recipe, which include a possible cooking disaster, an ingredient substitution, and an original idea.

With magnificent dioramic illustrations, Gilbert Ford captures the joy, creativity, and determination behind the invention of an iconic, one-of-a-kind toy: the Slinky! One day, a spring fell from the desk of Richard James, an engineer and a dreamer. Its coils took a walk…and so did Richard’s imagination. He knew right away that he had stumbled onto something marvelous. With the help of his wife, Betty, Richard took this ordinary spring and turned it into a plaything. But it wasn’t just any old trinket—it was a Slinky, and it would become one of the most popular toys in American history.

The doves flock together, nest together, and sing together. In the winter they travel south, in the spring they return north. Then one day a new bird flies on the scene. A big, noisy bird with twin engines and lots of legroom. The strange new bird ruffles the flock's feathers. But even as the doves turn their backs on him, their unwelcome companion makes himself quite useful. He might even teach them a new way to fly. . . . Gilbert Ford's debut picture book combines the right amount of silliness with a heartwarming message about finding one's place in the world.

These simple and mathematically elegant but practically useless prime number listings could have an appeal for afficionados of elementary number theory. They were prepared using a computer adaptation of the Sieve of Aratosthenes of Alexandria and the computations made on a small personal computer with an 8-bit microprocessor, a 64K random access memory, and a 2- megahertz clock. Computing time for checking 21, 380 integers and identifying the included 2400 prime numbers was about thirty minutes. This computational effort is quite modest compared to others such as two which are reported to have examined the first ten million integers. But the mere 2400 primes reported here, plus related items such as the number of prime twins and the integer gap between successive primes, are presented in tangible form.

After an initial qualitative characterization of the properties of explosions in the atmosphere and their blast and shock propagation effects, attention is given to the underlying quantitative principles of explosive energy release, including the scaling laws for explosions and internal blast effects from confined explosions. The dynamic loads that blast waves impose on representative structures are then characterized, with attention to resulting structural damage. A major feature of the present treatment is the use of the dimensionless Mach number in all shock equations ; a further simplification is furnished by first developing mathematical equations for shock in steady flow, and then applying these equations to explosive shock by simple transformation of coordinates.
