Science needs to be more accessible. That is what I try to do through my science blog. It's free, easy to understand, and I am accessible to answer questions. Science right now is obscured by many barriers of money, education, and language. This is true and a real problem.
But, scientists need certain jargon terms to efficiently, accurately, and specifically express concepts (that being said, any good scientist always defines terms that can't be googled or looked up in a free library).
When I talk about Vampire bats and their biosonar pulses, I make it known that I'm talking about the sounds they use for echolocation… but it's a lot more efficient to call them biosonar pulses (and that's what they are!). When I talk about quantum particles being 'entangled', I am already leaving out several years worth of math and physics education to begin to talk about a phenomena.
Every movement has its jargon. Even the social justice movement has its jargon. "Ableist", "ableism", "misogyny", "power structures", and "privilege" all have meanings in the social justice movement that are not always widely known to the lay public… and I have experienced this firsthand as an educator. In physics, "structure" can refer to spin states. In my research on colonialism, white privilege, and traditional dance, many people become confused when I use terms like those listed above to explain my project.
But sometimes, there is not a simpler way of expressing a concept accurately. Special attention must be given to situations with oppression, that being the primary concern. In the meantime, there will need to be patience on the part of the lay public and a spirit of earnest communication on the part of scientists and researchers.
