Einstein did it the hard way, but there’s a much easier approach to relativity.

Randal, Ken, and I discuss a host of topics around the future goal of uploading our minds into non-brain systems, to continue our mental lives and expand our range of experiences. The basic requirement for such a subtrate-independent mind is to implement whole brain emulation. We discuss two basic approaches to whole brain emulation. The “scan and copy” approach proposes we somehow scan the entire structure of our brains (at whatever scale is necessary) and store that scan until some future date when we have figured out how to us that information to build a substrate that can house your mind. The “gradual replacement” approach proposes we slowly replace parts of the brain with functioning alternative machines, eventually replacing the entire brain with non-biological material and yet retaining a functioning mind.
The Brain with David Eagleman

We are aware of how skewed our perception of reality is. How we see the world is shaped by our senses, our societies, and our knowledge.
And you may want to rethink your belief that science will always provide you with objective reality.
Physicists can now verify a hypothesis that Nobel Prize winner Eugen Wigner initially put out in 1961.
The study confirmed something that it was only a theory, namely that ocean water accompanies subducting slabs and thus enters the transition zone.
Ground-breaking research at Tel Aviv University successfully eradicated glioblastoma, a deadly form of brain cancer. The researchers achieved the result by developing a strategy based on their finding of two crucial mechanisms in the brain that promote tumor growth and survival: one shields cancer cells from the immune system, while the other provides the energy needed for rapid tumor growth. The research discovered that astrocytes, which are brain cells, regulate both methods, and that when they aren’t there, tumor cells die and are eliminated.
Rita Perelroizen, a Ph.D. student, served as the study’s lead researcher. She collaborated with Professor Eytan Ruppin of the National Institutes of Health (NIH) in the United States and was supervised by Dr. Lior Mayo of the Shmunis School of Biomedicine and Cancer Research and the Sagol School of Neuroscience at Tel Aviv. The study was recently published in the journal Brain and was highlighted with scientific commentary.
Desalination plants discharge brine and wastewater, which can also kill nearby aquatic life if the process is not done properly. And generating the large quantity of energy that the plants consume has its own environmental impacts until it can be done carbon-free, which is still years off in most cases.
Unaffordable Water From Costly Plants
Cost is another major hurdle. In most areas, the cost of ocean desalination is projected to remain considerably higher than the cost of feasible alternatives such as conservation for the next several decades, the timeline that utilities use when planning new investments. My colleagues and I found this in our research comparing water supply alternatives for Huntington Beach, even though we made favorable assumptions about ocean desalination costs.
