Every now and then I’ve had to calculate the results of a sieve test: I’d get the sieves and sample loaded on the shaker, run the shaker, then realize I’d have to start over because I forgot to get the empty weight of each sieve. Or I’d have to carefully brush out the sample onto a balance.
Of course, I also had to clean each sieve.
By the time I got every thing right and recorded I’d been interrupted and got the number wrong. A study in boredom and frustration.
If you’ve ever had to do a sieve test and calculate residuals and record the results, I think you might relate to this short video.
If you do sieving, I hope this touches a nerve and demonstrates a stress-free alternative. If that’s the case, please share this with your associates.
In my usual state of somewhere between total befuddlement and partial understanding, I’m still working on the puzzles of measurement.
