> It is ironic that the person who first described how hard spaceflight by rocket is, due to the exponential nature of the deltaV equation, is also the person who described the best way to side-step that problem with non-rocket launch.
It could also be used for recreating voices for people that have lost theirs, like Roger Ebert. I think he benefited by having so much of his voice already recorded, this would make it much easier for regular people.
> In fact, health officials say the virus is so contagious that if an unvaccinated person walks through a room two hours after someone with measles has left, there’s a 90 percent chance that an unvaccinated person will get the disease. People can spread measles for four days before the rash appears and for four days after.
- While it enters via the lungs, the virus emerges in the trachea, which positions it really well to be aerosolized through coughing. This aerosol and droplet transmission is really efficient.
- Measles is relatively stable in the environment, so lingers for a fair amount of time.
- It also appears to have a relatively small infectious dose.
Other highly contagious diseases, like norovirus, share fairly similar properties - you make a lot of virus, it hangs out for awhile, and you don't need to come in contact with much of it.
