Why Batch Testing and Contact Tracing Are The Two Keys To Stop The Lockdown Yo-yo

Back in March and April 2020, I (and many other economists) argued for lockdowns to get COVID-19 infections under control and to give health systems time to put in place testing and tracing regimes to contain the virus in the longer term.

Paramhansa Yogananda said: We are all of us a little bit crazy, but most of us don't know it because we mix only with people with the same type of craziness as our own. It is only when differently crazy people come together that they get a chance to find out the errors in their own types of craziness!

Electric vehicle sales have grown exponentially in recent years, accompanied by dropping prices. However, adoption of EVs remains limited by their higher sticker price relative to comparable gas vehicles, even though overall cost of ownership for EVs is lower.

Harley-Davidson is one of the most iconic brands in the world. Harley-Davidson, however, doesn’t sell motorcycles – it sells a lifestyle.

The problem is that data visualizations can also leave you with the wrong idea – whether the images are sloppily made or intentionally misleading.

Neowise is the first bright comet to be visible with the naked eye from the northern hemisphere since the mid-1990s. Another thing that makes this comet interesting is that it has a relatively long orbital period, meaning it was only discovered a few months ago.
