The word "regenerate" has got to be a bit of a stretch. It's not like decades of DNA mutations are going away. I've done fasts on relatively nothing for over five days. Early on, you get some "empty-stomach intell

If you believe what you think, you can be vocal unless you're a coward. Someone will likely be shot today because they wouldn't renounce some belief. Privacy advocates are not winning my sympathy in claiming that being watched a

I don't really buy the privacy paranoia anymore these days. It was the internet that first grew the distance between people so that we could pretend-anonymous say things about anything without repercussion an it will be the internet t

I did some back-of-napkin calculations on the Falcon 9's 1st stage numbers here: http://www.spaceflight101.com/falcon-9-v11.html Including the rest of the dry mass fraction of the vehicle, (the tank, the structure to

It's one more tool for achieving reuseability without sacrificing performance. The size and weight of an air-breathing system will be lower due to greatly increased Isp of the 1st stage, the largest stage by mass. A smaller 1st stage

Now that I'm back interested in the topic =D.. F404 is just not quite at 10:1 T:W, which just goes to show that even COTS parts these days can make a very high Isp 0.5 stage.

T:W for rockets vs air-breathing are really skewed by fuel consumption. Falcon 9's Merlins will burn ~25-30k lb fuel (70% launch mass is 1st stage gas?) per minute (180s total 1st stage time) vs ~1k lb fuel per F119. The jet engine w

Yeah, definitely you would look for either a very short-lived (2min) 1st stage or 0.5 stage. Max q is what makes it seem right. An STS flight profile can't even use max thrust again until 50k ft and Mach 2. Turbojets peeling away and

Haha, right. I am not sure that a typical rocket body can handle the moment loads of being slung under a wing, even a delta, so I don't know about trying to fly an entire rocket, but certainly I'm advocating an even more modular

The separation velocity they chose for the first stage is very promising. Given the cheap cost of fuel and difficulty of making the 2nd stage body able to survive the much-higher re-entry velocity, I wonder about separating just the engine

Someone use drones already. Whoever is using drones to launch many air-breathing components that return on their own and launch stages that glide in after re-entry wins. The rest of this stuff has obvious gigantic weight disadvantages. Cu

Build something. Nothing leads to prioritization like optimizing brutally for ROI on time. Is it the most pertinent thing you can be doing? When you really lock yourself into a lean-startup REPL of building, measuring, and repeating, val

It's about putting money into hands of people actually doing things instead of owning or controlling things. This process itself makes money. It's taking advantage of a market imbalance. This is how you disrupt. You can be a V

Most large companies with well-oiled legacy systems actually are not that bad to work with. I've seen the guts of a large PHP system, and while it was still re-inventing the wheel all over the place, they had still solved all of their

Rovio still plans to release an animated Angry Birds film in 2016. We might be over-milking this one as a society at that point. I would put my money on... something else, specifically just not more Angry Birds.
