![]() ![]() Still, the authors hope their work "can inform future studies that will close these gaps in our understanding about COVID-19," Mittal said. They acknowledge that their model makes a number of assumptions, and it includes key unknown variables. Notes on this equation, also known as the Drake Equation (in case you want to look that up on. Explore the answer with the Drake Equation. ![]() Check it out here, Episode 23 Counting Aliens with the Drake Equation. But you can play with the values in the calculator below. Could there be intelligent life on other planets This question has piqued imagination and curiosity for decades. We have recorded an entire episode of Astronomy Cast about the Drake Equation. The researchers note that they intended their model to be simple and intuitive so that it could be accessible not only to scientists but policy makers and even the general public. Check out this Drake Equation calculator. "This kind of scaling or rule can help inform policy." Drake Equation Calculator Created by Frank Drake in 1961, the original Drake equation was designed to calculate the number of intelligent communicative species which could be expected to exist in the galaxy. "If you double your distance, you generally double your protection," Mittal said in a separate statement from the journal. In that confined space, the risk of transmission increases by a factor of 200," compared with a scenario in which people aren't exercising, Mittal said.įor social distancing, the researchers found that there was a linear relationship between distance and transmission risk. The infected person is expelling more droplets, and the noninfected person is inhaling more droplets. "Imagine two people on treadmills at the gym both are breathing harder than normal. In this new effort, the researchers have expanded on research done by Frank Drake back in 1961. ![]() In a scenario in which people are exercising vigorously, such as at the gym, the transmission risk skyrockets, the model found. Their resultant calculation concludes there are more than thirty current technological civilizations in the galaxy (disregarding error bars). Surgical masks may reduce transmission by a factor of 10, and cloth masks by a factor of 7, if both parties are wearing masks. For face masks, the researchers estimated that, with all other factors being equal, a scenario in which both infected and susceptible individuals are wearing N95 masks could reduce the transmission risk by a factor of 400, relative to a scenario in which both people aren't wearing masks at all. ![]()
