--  2249  - Everyone is a manager.  This review refers to managers of managers but it can be interpreted ton apply to teachers, coaches, parents, even big brothers.  Experience is a great teacher but you get the learning before you get the lesson.

-  2250  -  We have several spacecrafts visiting asteroids right now. January, 2019.  This Review  will summarize the current visits and then get into the history even some that are evident on the Earth and on the Moon.
-  2251  -  Hydrogen trains have already replaced more polluting diesel engines on a line in Germany, and some train companies think the vehicles could be running in Britain as early as 2022.
-  2252  -  Here is a summary of the space program activity in 2018.  The search for exoplanets continued with Kepler and a new TESS spacecraft that just started the search.  Two other spacecraft visited two different asteroids.  Their mission is to complete measurements then collect samples to return to Earth.  Missions on Mars and studies of gravitational waves are also in this Review.  Request 2252 if interested. 
-  2253  -  Expanding Universe, how can it be flat?  The universe is expanding, it’s not just that objects are moving away from one another, but the fabric of space between objects is itself expanding! And,  the expansion is accelerating! It is assumed that dark matter and dark energy are responsible for this accelerating expansion. 
 -  2254  -  Cepheids give us the astronomical ladder used to step by step determine the distance to stars and galaxies.  Cepheids are milestones of brightness.  Cepheid stars are pulsating variables stars.  Their brightness and dimness pulsation rates, or periods, correspond directly to their intrinsic brightness.  From brightness we can use these steps to calculate distances across the Universe.
-  2255  -  The history of the atom continues.  It starts in 1803 with molecules, then atoms, then atomic nuclei, then sub-nuclear particles, then antimatter and the possibility of an anti-Universe.  The study of the ever smaller has taken us to the ever larger.  And, the history of the atom continues.
-  2256  - The stability of all atoms, in all the elements, in all of matter, depends on the Principle of Uncertainty and the wave-particle duality of all matter.  This review will use the Uncertainty Principle to calculate the ground energy state of the atom.  The rest state of all atoms can not be zero.  If it were zero all atoms would be unstable.  Instead, the rest state of all atoms is some specific energy level we can express in electron-volts.
-  2257  -  What is the fate of our Universe?  The key to unlocking our ultimate cosmic fate is dependent on our understanding what we are looking at   And then ensuring that our answers aren't biased by the assumptions we're making about the objects we're measuring. Dark energy may not be a constant.  Stay tuned, an announcement on the fate of the Universe will follow
