Science has made leaps and bounds in recent decades with the development of sophisticated instruments that measure deeper and deeper into our world. Discoveries can now be made that confirm the existence of gravitational waves, the structure of proteins and everything in between. This is a golden age of scientific exploration.
And yet there isn’t a laboratory in the entire world that could function adequately without such equipment as a marker pen.
When we talk science and stand in awe at our capabilities and technological advances, it’s easy to forget that much of science uses very rudimentary equipment. Particularly in applied science where a new project with industry means having to measure a characteristic of a real world sample right now.
This includes, for example, the level of sediment in a tank. How do we measure it? Get out a marker pen and draw a line on the tank where the sediment comes up to. Genius.
Or when we need to compare the filterability of samples too small for the real method, how do we do it? Pour the sample through the filter paper and mark the receiver flask with the volume filtered every 10 seconds. Marker pen wins again!
The genius of early scientists was in developing ways measure the world around them. Today determining the structure of an unknown molecule, for example, is very straightforward, as long as you have a nuclear magnetic resonance spectrometer and mass spectrometer handy and really, who doesn’t? But a century ago this was a real challenge and involved a massive array of indirect measures to get the final structure. And some genius. That always helps.
Even in modern labs, it is an invaluable skill to be able to develop practical and reproducible methods on the fly using everyday, inexpensive lab equipment. Sophisticated equipment is essential but expensive and any cost savings to a research budget is applauded.
Particularly if there is a solid element of ingenuity associated with it. Like rigging up a large hadron collider in the basement using rubber bands and lengths of pipe. I think that might have actually been a Macgyver episode.
While high tech science paves our way to a deeper understanding of the universe, we must remember that it is also the simple things in science that help push that knowledge forward.
