Signal processing, it’s complex, there are a million ways to go about processing a signal, and like life, there is no best way to go about doing it. Trust me, it is as frustrating as it sounds. Today’s scratch pad note is on power spectral density or PSD for short. So let’s dive in.*
Part of getting an education isn’t about learning what to think, it is about learning how to find good information. When it comes to scientific literature [especially on-line], it’s hard to separate the good from the bad if you don’t know what to look for. With the emergence of pseudoscience in the mainstream I think it’s important to go over a few red flags when it comes to claims being made.
Ever hear if it is too good to be true, then it probably it probably is? Well that seems to be the case for the not so latest news for stem cell research.
Just weeks ago, the science world was buzzing when Japanese scientists announced that it had discovered a novel way to produce stem cells that was free of controversy, cheaper than traditional methods and simple.
You’ve seen a swarm of bees, you’ve seen a swarm of ants. But now, a research group at the Harvard School of Engineering and Applied Sciences have introduced us to a new kind of swarm, a swarm of robots.
The idea stems from, of all things, termites.
Normally, when you have any sort of large scale building operation, like a home for example, you have someone in charge telling each individual what to do. There are specialized functions for each person, a electrician, a carpenter, etc and if one of them walks out on the project, the project is stalled until they are replaced.
Does Vitamin C actually cure cancer?
Well, no, not quite. But new research shows that vitamin C can improve the response of the chemotherapy drugs. The tests, which have primarily been done on mice and in the lab, show promise for future options in treatment.
Vitamin C, which is water soluble, easily passed from the body, and has low side-effect risk might be the key to better cancer therapies. If larger trials show promise, this could prove to be a low-cost addition to treatments already in place.
Or my personal favorite Heisenberg gets pulled over by a police officer, officer says ‘Do you have any idea how fast you were going?’ Heisenberg replies ‘No, but I know EXACTLY where I am.’
