That鈥檚 a classic quote spoken by Jimmy Stewart鈥檚 character, George Bailey, in the 1946 film It鈥檚 a Wonderful Life.
One 成人头条 State professor does it for students every week.
Martin Ratcliffe, adjunct professor in the Dorothy and Bill Cohen Honors College, teaches students that space and the people who study it aren鈥檛 all that far away.
鈥淪cience, in many ways, is remote to people, but it鈥檚 a subject practiced by real people with real lives. I try to bring some of that humanity to the story,鈥� Martin said.
Martin has a keen interest in staying up to date with modern astronomical research. Sometimes he talks to his students about scientists he has met at conferences.

That鈥檚 two degrees of separation between students and leading scientists like Space Shuttle astronaut John Grunsfeld. Martin met Grunsfeld at a conference and witnessed his 2009 launch on the shuttle 鈥淎tlantis鈥� to service the Hubble Space Telescope.
If a student wants to contact Grunsfeld or another astronomer, Martin will gladly give them an email address.
鈥淭hey have a passion too, and they鈥檙e not locked in an ivory tower. They have breakfast and they shower in the morning. Then they go to work and try to figure out why particles have mass,鈥� Martin said.
No big deal.
Martin makes the world a little smaller for students, but through his classes 鈥淒ynamic Universe鈥� and 鈥淏ig Bang and Black Holes,鈥� he instructs that the universe literally gets bigger all the time.
Some form of energy pushes galaxies away from each other at an accelerating rate, but we can鈥檛 see it. Cosmologists and astronomers simply call it 鈥渄ark energy.鈥�
It鈥檚 far from simple.
鈥淗ere I am at a university teaching cosmology, which is a very complex subject, to people who may not have a science background. That鈥檚 what I enjoy 鈥� teaching that subject in a way that everyone can understand.鈥�

One would think that teaching concepts like the expansion of the universe would require advanced math and theory.
鈥淚 use analogy. I use descriptions. I use visuals that hopefully make people feel like this is totally above their heads 鈥� literally 鈥� but is something that we can understand using basic principles.鈥滿artin uses other methods that he learned during introductory cosmology courses at the University of Chicago. The courses were designed to spread cosmology information farther afield.
His teaching style isn鈥檛 only for students鈥� benefit.
鈥淚 simplify it for a reason because I can鈥檛 teach the complex stuff either.鈥�
Martin avoids diving into relativistic physics. He leaves that to researchers and encourages students who want to learn more to visit the Physics Department.
He hopes that students are able to realize that by applying simple principles, they can understand how the universe works and how it originated.
It鈥檚 not just conjecture. It鈥檚 scientific and observable.
During one class session Martin took the class outside to view Venus in broad daylight. People walking by stopped at the sight of 20 students pointing straight up in the sky.

鈥淭he height of human achievement is to put together a model of how the universe works,鈥� Martin said. 鈥淣ot just a model that is the thinking of the mind, which is how we鈥檝e done it in the past. That鈥檚 how philosophers brought that model of the universe around. This is model is supported by direct observation.鈥�
Direct observation is Martin鈥檚 game. He owns his own telescope, a 14-inch reflecting telescope mounted on a computer-controlled mount. It鈥檚 housed in a shed in his backyard.
At least once during every course he instructs, Martin invites the whole class over to view objects in deep space, from nebulae to galaxies. The shed鈥檚 roof rolls off to let the telescope absorb starlight.
Martin is also collaborating with Bethel College to use their 16鈥� rooftop telescope to develop more research opportunities for WSU students.
He and the college have completely restored the telescope with new stabilizing equipment and computer controls, so Martin and his WSU classes will be able to remotely use the telescope from campus.
鈥淚f you want to know how we know the universe works just as an interest and background to expand your knowledge, come to the Honors College and I鈥檒l teach it,鈥� Martin said.
In addition to his work as an adjunct faculty member at WSU, Martin works for the planetarium software company Sky-Skan. He came to 成人头条 to direct the construction of the Cyberdome Theater at Exploration Place, and stayed here as a planetarium director. Martin also does astro-imaging with his telescope, and travels across the world to capture rare astronomical sightings such as the 2019 total solar eclipse in Chile.
