  • If you measure response curves of individual cones and rods you won’t see any of the parameters go below the ms range, probably not even below 10ms. However the retina does receive bright short pulses as longer averaged signals. All the very high Hz vision cases see information of the same “object” spread over many cells in the retina. A trail showing up as many distinct images vs a long smear.

    If you couldn’t move your eyes the limit would be lower, but because you can’t the rendering cannot anticipate those effects and emulate them. Motion blur is what happens when you always “anticipate” the eye to remain static. If you could measure eye movement extremely well and react within well under a ms, you might be able to match motion blur to eye movement of a single person. Add a second observer and it already breaks down. Not that our sensors are anywhere remotely near making this possible.

    Edit: I suppose this would mean if you integrated a display into contact lenses and got the latency right you would max out at lower Hz.






  • fact is:

    The US dollar index, which tracks the greenback against a basket of six major currencies, has risen by just under 3% since the end of last month. The dollar’s surge against the euro has been especially emphatic, at just below 3.5%.

    us media claimed:

    The dollar’s strength is largely being “driven by demand for so-called safe-haven assets”, the Wall Street Journal said. Reuters was even more emphatic: “Dollar reclaims safe-haven mantle,” read one headline, among many similar ones.

    brussels thinktank instead points out:

    The US, a major oil and gas producer, has seen its currency surge as its export prices have risen, driven by the war’s negative impact on the world’s energy supply. Europe, conversely, is a net importer of fossil fuels, pushing the euro lower.

    Most damaging for the ‘safe haven’ narrative is, however, the fact that US Treasury yields have actually risen since the start of the war. This is the exact opposite of what a genuine flight to safety would produce, as stronger demand for US debt would push Treasury prices up and yields down.
