Robin Barooah gradually weaned himself off coffee and found that his concentration actually improved. He explains how he did it and what he discovered on the Quantified Self blog, which covers news about self-testing and self-monitoring.
As part of a separate experiment, I have been keeping track of the amount of time I spend working on projects. I work in 25 minute intervals which I time with a coffee timer, and I mark an X in a paper journal for each interval that I successfully complete. If I get distracted, I don't mark the X, and if I can't concentrate, I abandon it and don't mark an X rather than sitting out the timer. I've been doing this since the end of June, so I tabulated the data and created a graph of my hours of concentration per day, and overlaid a bar showing when I drank my last coffee.
Causality is a complex issue. Obviously this is an n=1 experiment and I am intentionally doing other things that may well be improving my concentration, but one thing is very clear; the amount of time I spend concentrating has not deteriorated since I quit coffee, so I can easily reject the hypothesis "I need coffee to help me concentrate."
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
This is so amazing. Watch what happens when a blacksmithing anvil is lowered into a large vat of pure liquid mercury. Update: One of our readers posted the link to the original video in the comments. I have replaced the animated GIF. Thanks, Crispy75. [H/t Alberto Gaitán via Bryce Lynch] Image: Screengrab from GIF
You’d be surprised anyone would have to say this, but…there are plenty of items that don’t belong in a suitcase. Like a bag of dead birds. No, really…people are actually packing bags of small dead birds into their luggage these days. Look, we can’t tell you how to pack. That’s your business. But we can […]
Presidents’ Day and VPNs may not be a natural fit at first glance. But think about it for a minute. George Washington and Abraham Lincoln were both American presidents whose legacies are forever tied with liberty and freedom. And what is a VPN service if not absolute web liberty and freedom for all your digital […]
You hear the stories all the time. You know the ones about how a new vehicle instantly loses hundreds, even thousands of dollars in value the second a new owner drives it off the lot. Depreciation is a killer, especially when the item itself works just as well — or maybe even better than all […]
