I have this belief that antiparticles such as positrons are actually particles traveling back in time. There are a lot of reasons for this such as the fact that their time evolution contains a minus in front of the t.
However there are not a lot of antiparticles in this universe dominated by normal matter (for reasons I will not get into right now). I think this is one of the possible arguments to why we only see into the past and not the future – there is only the most tenuous influence from the future, and not something humans can perceive. Plus we are constructed from particles evolving forward with time and everything around us is just normal matter, also traveling forward.
You can also see this as a vast amount of information flowing from the past to the future but only a few bits traveling the other direction.
One can think of particles and antiparticles and being like corkscrews in time; the difference being whether they have left or right handed rotation. This is also like a clock turning clockwise or anti clockwise. And for example if a gamma ray turns into an electron-positron pair, one can also picture that as a positron traveling back in time, colliding with a gamma ray and bouncing forward in time phase reversed as an electron.
Anyway I think it might be interesting to test this by building a space based telescope that can create a 2D image from the arrival of antiparticles and another coincident one creating an image from the arrival of particles.
The question is whether these two images will actually show more or less the same view of the universe, or if the antiparticle generated image will show a more evolved state of the cosmos. Interesting to propose. I hope that someone has the influence to make such a project happen.
(Also if it’s happening and I don’t know about it, let me know!)
The new European GDPR personal privacy data laws allow users to ask any company to delete all their personal data and to provide a copy on demand. Non-compliance leads to harsh penalties.
Those laws don’t make any sense (in that it is impossible to comply) for companies that are developing any kind of machine learning / neural networks / artificial intelligence that learn global models of any kind from attributes gathered from multiple users. This is why:
Lawyers expect that personal data is localized and understandable. But increasingly we are aggregating personal data into all kinds of computer models about users where that data becomes diffuse and incomprehensible.
Just think of it as someone asking you to forget they ever existed and to roll yourself back to whatever you would have been like if you had never had any contact with them, and also they want an exhaustive list of the personal neural mental data you are currently holding on them in a form that they can understand.
It’s important for users to know that, as technology is progressing, their data is being utilized in ways that cannot be undone, and that a request for the stored data is becoming impossible to fulfill. However lawyers and regulators should also understand that aggregating personal data in machine learning algorithms can be an effective form of anonymization.
Adobe likes to take over your computer, especially if you have installed a number of products, or enrolled in Creative Cloud. There will be many Adobe processes running all the time and various ones running at startup or login. Adobe is well known for creating buggy products with security vulnerabilities, like Flash, and running many processes that bog down your machine. I just wanted to be rid of them altogether. Here’s what worked for me on a MacBook with OSX 10.13.4.
The goal is to get the following results at the terminal command line: find ~/Library | grep -i adobe returns no results; ps aux | grep -i adobe returns only the ps command itself; find /Applications | grep -i adobe returns only other applications that reference Adobe in some passive way (in my case Xcode has some Flash related libraries); and most importantly launchctl list | grep -i adobe returns no results.
The first thing that I personally had to do was to pay over $100 to terminate my Creative Cloud contract with Adobe. Hopefully you don’t have to do that.
To begin this journey, ensure that no applications are running except for a finder window and a terminal window, and maybe this blog entry copied to a text file (not PDF), or printed.
