Thanks for all the responses.
This specific silicone grease,as i mention above,is not sold as a plumber grease,it is sold as lubrication(among others)of diving equipments(o-rings,zippers etc.)
and when i looked into the MSDS,it seemed to me as it is okay to use
on faucet O-RINGS that are in contact with potable water.
But as i didn't see any kind of approval standard on the package or in the MSDS ,i thought that i better verify this with you.
My assumption was that if the item doesn't have a label that indicates that it is approved for use with potable water,it doesn't necessary mean,that it is not safe to use with potable water and the MSDS information is what matters,as the company maybe didn't add an approval standard due to other reasons(like economy reason etc.),even that it actually safe to use with potable water,
Am i right?
Yes,the washing liquid will help it on and it won't leave not residue,but
as much as i know:
The addition of a lubricant can extend the operating life of the O-ring by creating a barrier film over its surface. This barrier film can also help reduce leakage by filling the asperities between the metal surface and the O-ring seal.
The stuff I have is bottled for gym equipment use.

PDMS's safety profile is pretty good. It was used as a breast implant substrate iirc. I use it as a water proofer on my boots.

The specific claims matter. They probably say something like “a quantum computer with a sufficient number of qubits will be able to crack RSA in a short amount of time”
“The current estimate is that breaking a 1,024-bit or 2,048-bit RSA key requires a quantum computer with vast resources. Specifically, those resources are about 20 million qubits and about eight hours of them running in superposition.”
We aren’t anywhere close to having such resources.
The main unknown seems to be whether AI will provide useful hints to the AI solutions, and that affects the projected time.

From the 2017 Hamas manifesto:
Quote16. Hamas affirms that its conflict is with the Zionist project not with the Jews because of their religion. Hamas does not wage a struggle against the Jews because they are Jewish but wages a struggle against the Zionists who occupy Palestine. Yet, it is the Zionists who constantly identify Judaism and the Jews with their own colonial project and illegal entity.
It seems from this Intercept article, some of our politicians seem to refer to the 1988 manifesto that called for elimination of Jews from Palestine.
QuoteDO THE PEOPLE who run the world know the most basic facts about the world? This urgent question is raised by a recent columnOpens in a new tab on the Israeli attack on Gaza by the British politician Ben Wallace, who, until a few months ago, was the United Kingdom’s defense minister. Terrifyingly enough, the answer appears to be no.
The problem is that Wallace places great significance on Hamas’s original 1988 charterOpens in a new tab, which is explicitly antisemitic and rejects any coexistence with Israel. But he doesn’t appear to know Hamas issued a new charterOpens in a new tab in 2017. In it, Hamas affirms that its “conflict is with the Zionist project not with the Jews because of their religion.” And, while the revised charter rejects the legitimacy of Zionism, it accepts “the establishment of a fully sovereign and independent Palestinian state, with Jerusalem as its capital along the lines of the 4th of June 1967, with the return of the refugees and the displaced to their homes from which they were expelled, to be a formula of national consensus.” This reference to the lines of June 4, 1967 — before Israel captured the West Bank and the Gaza Strip in the Six-Day War — is regarded as accepting the existence of Israel within the borders it had at that time.

I don't know the details, but Shor's algorithm is a quantum algorithm for finding the prime factors of an integer. This would allow private keys to be determined from public keys much faster than any known classical algorithm.
As someone put it: from billions to millions of years.

As with so many such situations, land is key. And displacement often is run on the principle that my people can make better use of that land than you do, we are better, more civilized, and some ancient text proves it!
I remember my grandad presenting that argument. I didn't like it then and I don't like it now. It's like saying: "You are a crap driver, I think I deserve your Bugatti more than you"

At the end of the day we are testing thoughts out and, hopefully, using the responses to refine those thoughts. Sometimes it can feel like people are ganging up when the opposing numbers are significantly asymmetric, but we are all actually individuals with our own views... as has been demonstrated many times between each of us. Conversational frenemies.

@MigL We have been talking about this for a long time. On Saturday, he has admitted, all the efforts towards a two-state solution were for nought.... and he's 'proud' to have held it back. It's there in black and white. Here's the pertinent part:

We may never know. Why do scientists believe that the unfathomable number TREE3 is not infinite?
If you are walking along a sandy beach, and you scoop up a handful of sand, how much about our universe does that little handful of sand tell you? It tells us about the minerals in sand and some other things, such as the atomic structure of this kind of matter. It does NOT tell us about EVERYWHERE in the universe. Our observable universe is just a handful of sand, in a universe that extends to infinity in every direction (assuming a flat or hyperbolic universe). Our observable universe is a tiny pinprick in the vastness of infinity. For this reason, I think that our universe, the large-scale, sponge-like structure we see is probably finite. It just becomes less dense in one direction, until there is no matter at all, and empty space until you reach the edge of an adjacent big bang.
The universe stops fractalizing beyond a certain scale and becomes homogenous.
QuoteWe have made the largest-volume measurement to date of the transition to large-scale homogeneity in the distribution of galaxies. We use the WiggleZ survey, a spectroscopic survey of over 200,000 blue galaxies in a cosmic volume of ~1 (Gpc/h)^3. A new method of defining the 'homogeneity scale' is presented, which is more robust than methods previously used in the literature, and which can be easily compared between different surveys. Due to the large cosmic depth of WiggleZ (up to z=1) we are able to make the first measurement of the transition to homogeneity over a range of cosmic epochs. The mean number of galaxies N(<r) in spheres of comoving radius r is proportional to r^3 within 1%, or equivalently the fractal dimension of the sample is within 1% of D_2=3, at radii larger than 71 \pm 8 Mpc/h at z~0.2, 70 \pm 5 Mpc/h at z~0.4, 81 \pm 5 Mpc/h at z~0.6, and 75 \pm 4 Mpc/h at z~0.8. We demonstrate the robustness of our results against selection function effects, using a LCDM N-body simulation and a suite of inhomogeneous fractal distributions. The results are in excellent agreement with both the LCDM N-body simulation and an analytical LCDM prediction. We can exclude a fractal distribution with fractal dimension below D_2=2.97 on scales from ~80 Mpc/h up to the largest scales probed by our measurement, ~300 Mpc/h, at 99.99% confidence.

Photons have no rest-frame energy because photons have no rest frame.
Does that mean that travelling at c is an intrinsic property of massless particles for them to exist?

One of the more sad and horrible war stories I've heard, and that's saying something. It's the kind of story that sends me back to my core opinion on human aggression: you cannot trust humans with anything more lethal than a stick.
It smells of a de facto, if not explicit, shoot-to-kill policy.

Democraty is self-eroding. One of its main flaws is that it demands those in most power must represent and emulate those in least power, rather than an intellectual oligarchy from the most knowing. It must be done away with.
Intellect is no guide to societal stability. Intellectuals are not necessarily inherently good and accommodating to all viewpoints; they are as vulnerable to deceiving and self-deceit as anyone else.

Is that because you want a repeat of the Holocaust? Because that's about as accurate as CharonY's assessment...and apparently yours also.
We aren't looking to prevent another Israeli-focussed 'Holocaust', which is not the issue, we wish to avoid seeing a repeat of NAKBA 1948.

Whale conservationist Ted Cheeseman admits that the huge animals don't patiently pose for photos.
Instead, on most whale-watching trips he says "you see 2% of the whale for 2% of the time".
Nevertheless, going out in a boat to try to spot a whale remains very popular.
An estimated 13 million people go whale watching every year around the world, and the industry is said to be worth $2.1bn (£1.7bn).
The humpback whale is the star of the whale-watching business, as it's relatively common and spends time on the surface. Mr Cheeseman also says that the humpback is "very engaging", with the luckiest whale-watchers catching a breach (a jump out of the water) or a flick of the tail.
To help people feel a closer connection to each whale, Mr Cheesman's research company, HappyWhale, allows users to upload their photos onto its website.
HappyWhale's artificial intelligence (AI) software will then quickly trawl through its database of more than 70,000 different whales with the aim of telling you the exact animal that you were looking at.
It can tell you the whale's name, if it has already been given one, or invite you to choose one. And if the whale is one that has been previously recorded it will show you a map of everywhere that it has been sighted.
The AI works by using adapted human facial recognition software to identify each whale's uniquely shaped, coloured or marked tail.

Pain is a mental phenomenon. It clearly influences brain state.
Love is a mental phenomenon. It clearly influences brain state.
Hunger, fatigue, confusion, optimism, depression… all mental phenomena, all influence brain states (which are themselves in perpetual flux).
I’m sure there’s some arcane super micro precise nonstandard usage definition of causal here that I’m ignoring though.
I'm with you here. It's not a linear process. Sometimes, when one goes especially deep we can lose the sight of the forest. At the micro level, individual processes may be linear and sequential, but zoom out and the story changes to a more complicated one.
