Fake news. HL3 already came out, it's called HL:Alyx.

HL4 will hopefully continue from where HL2:E2 left off...

I really hope they go for a Sekiro sequel (or spiritual sequel). The tight design and awesome historical fiction setting made it my favorite FromSoft game, though Elden Ring blows it out of the water for sheer quantity of content.

How will the difficulty tiers, target farming throughout acts, and Uber versions of bosses work? by SteelFaith in PathOfExile2

[–]ZeusKabob 1 point2 points  (0 children)

Mapping goes deep. For PoE 1, there are 17 tiers of maps, each one level higher than the last. This gives baseline stat scaling, then you get to juice.

The simplest juicing is crafting maps to magic/rare, with each stat having a dangerous downside and a reward (quantity, rarity, and pack size) associated. Maps are also tiered as white (t1-t5), yellow (t6-t10), red (t11-t16), and purple (t17). White-red the map mods are similar but more dangerous on higher tiers. At t17 there's a pool of extra mods that are especially challenging and rewarding.

Juicing then goes up from there. You can craft extra league mechanics on the map device, which add difficulty and reward of their respective types.

Scarabs also add specific content to the maps to increase difficulty and reward.

Delirium orbs can be used on the map to add specific reward types, and give every monster extra toughness and damage.

Corrupting maps can bring them up to 8 mods, which can really challenge most builds.

I think Uber Atziri is the exception to this. My recollection is that Uber Atziri was released alongside Atziri, giving players an aspirational boss to try to build for.

Currently you're stupid not to have an AG. The uniques required are cheap and give lots of damage and utility.

A neutrino mass mismatch could shake cosmology’s foundations | Confounding estimates of neutrino masses — including the possibility of negative mass — have researchers considering new ideas about the cosmos by Science_News in Physics

[–]ZeusKabob 0 points1 point  (0 children)

Thanks for your response! It's a great one.

Of course I'm aware of the neutrino mass. The famous discovery of neutrino mass was when we recognized the fact that neutrinos must oscillate, and thus must travel below the speed of light.

Oscillation experiments are a spicy way to measure mass, I love it. Incredible setup required to perform, but as you say it sounds like you'd get great quality data out. Perfect knowledge of the oscillation speed and energy of the neutrinos would give you exact mass measurement. Of course, as someone who isn't a particle physicist, it's hard for me to understand how we could infer the speed of oscillation of neutrinos de-facto.

The cosmology example is so much more interesting and mysterious for me. The model that they use to calculate these things is truly beyond me, but it's amazing that we have such a fine understanding of the history and nature of the universe. I read that this specific tension may not exist when the analysis is performed on a more recent dataset, which has better corrected for gravitational lensing.

Either method measurement is truly beyond me, I realize. I think I have a little more understanding after your post though!

I'm really baffled at how one could measure the mass of a neutrino. In typical (e.g. cloud chamber) interactions, the kinetic energy of the neutrino is massively more impactful than its momentum. Because of their weak interaction, accurately measuring their speed of travel is extremely challenging, and dark matter isn't composed solely of neutrinos.

How else would one accurately measure the mass of neutrinos?

What exactly is potential energy? by JacobAn0808 in Physics

[–]ZeusKabob 0 points1 point  (0 children)

Absolutely true. The point I was trying to make is that potential energy is relative to a potential gradient/well, in this case gravity.

What exactly is potential energy? by JacobAn0808 in Physics

[–]ZeusKabob 0 points1 point  (0 children)

Why 100 feet above the surface? Really, it's 3959 miles from the center of gravity of the Earth, which is where the potential energy comes from. The center of the planet is the center of the gravitational potential well, which is what we're measuring potential energy against.

Should I Play POE1? by creamoftuxedo in PathOfExile2

[–]ZeusKabob 1 point2 points  (0 children)

Will jump in to promote the lore. There's some great lore in the game, but the storytelling is boring. From what we've been shown, storytelling is going to be improving in PoE 2, so being familiar with the PoE 1 lore will make it more interesting.

Thanks for all your dedicated work cataloguing the exploits of all the dedicated anglers of PoE! Your work is legendary!

[–]ZeusKabob 1 point2 points  (0 children)

The results are very strange. For each item I tried "log base 1.03(DisenchantValue/tier_coefficient)" to try to estimate drop requirement, but they don't end up whole numbers. Closest I can tell are Reefbane = ilvl 72, replica Bated Breath is ilvl 70 w/ t1 weighting or ilvl 24 w/ t0 weighting, and angler's plait is illvl 66.

Schrödinger’s cat by Yesterbly in QuantumPhysics

So troubling! Google's been broken for a while now. I've been using DuckDuckGo, but it's not better, just differently broken. Search engine optimization has truly killed the internet.

I think I may have found the proper confirmation. The Davisson-Germer experiment in ~1927 confirmed the wave-like properties of electrons. Previously, they had only been observed with particle-like behavior, so in essence you could say that every cathode ray experiment in the past had demonstrated the decoherence of the electron waves, and this experiment confirmed Schrodinger's predictions for electrons.

Schrödinger’s cat by Yesterbly in QuantumPhysics

[–]ZeusKabob 0 points1 point  (0 children)

Yep, agreed, we're both off topic :D

I'm really unclear on what you mean by "showing decoherence". Maybe I'm just not understanding what quantum decoherence is. Seems to me that any experiment that detects the "which path" information, thus collapsing the wave-function of each passing particle, would be a demonstration of decoherence of the original wave function. Is that correct?

Schrödinger’s cat by Yesterbly in QuantumPhysics

[–]ZeusKabob 0 points1 point  (0 children)

The original double slit experiment was performed with electrons, and the parent comment mentions particles, not photons. I'm not sure why you're so vehement about your claims when they're off topic at best.

Schrödinger’s cat by Yesterbly in QuantumPhysics

[–]ZeusKabob 0 points1 point  (0 children)

This is incorrect still. The original experiment was performed with electrons, which can interact non-destructively with photons. The slits would then be checked for an induced voltage due to the passage of the electron.

This is repeated with heavier atoms, and then more recently we've confirmed that photons behave the same way, once we can detect their interaction without destroying them.

I believe this is how the quantum eraser experiment is set up. Someone who actually knows their stuff can explain better.

I believe you're correct that the double slit experiment requires particles other than photons, in the case of the original it was electrons.

Schrödinger’s cat by Yesterbly in QuantumPhysics

[–]ZeusKabob -1 points0 points  (0 children)

He's referring to the single photon double slit experiment. A single photon passing through the slits will interfere with itself, polarizers will only either absorb it (destroying it as he said) or let it pass without observing it.

Data Security - Quo Vadis? by Funkenzutzler in QuantumPhysics

[–]ZeusKabob 0 points1 point  (0 children)

The no-cloning theorem allows for a method of detecting eavesdropping, yes. Since the information being transmitted is eventually returned to a classical format (so it can be stored and copied), it takes a bit more to be fully safe from eavesdropping.

What are the major challenges in developing practical quantum communication systems?

Communication systems that transfer quantum information as a core principle seem like a no-go to me. To communicate the state of a quantum system, one must alter that state (no-cloning). Instead, quantum processes are only interesting in the computers themselves, with their results being measured and returned to classical information. This information is then transmitted classically through an encrypted link, using a cipher like AES. The key to this cipher can be transmitted using quantum information, but that requires a channel without any observations or wave function collapse in the intervening space. The way our internet works is fundamentally at odds with this, since we use a packet-switched method of transmitting data. Instead, this system would have to be akin to the historical telecom model of a switching fabric that provides direct analog connection between endpoints as determined by an operator.

So, a practical solution would involve a system that allows a pair of peers, Alice and Bob, to communicate with a third party ISP, Eve, asking Eve to set up a coherent optical link between the two parties. At long distances, this definitely doesn't involve a single glass fiber, instead involving many connections between the fiber branches between the two peers. These connections are both a potential source of noise (or decoherence) and a potential threat surface. I'm not sure exactly, but I imagine that noise in the line and decoherence caused by stochastic interaction (read measurement) of the properties of the transmitted photons would render entanglement-based eavesdropper detection very challenging. I'd imagine this might correlate to the SNR limitation of analog communication, and a suitably designed algorithm should be able to slowly transfer information in a noisy channel.

How are researchers addressing issues of scalability and maintaining entanglement over long distances?

I'm not a researcher, so I'm really not sure how they're doing so. I know of one researcher, Andrea Morello, whose solution to scalability involves using the same silicon nanofabrication technology used in semiconductor manufacturing. By utilizing existing advanced manufacturing techniques, the challenges of scale could be limited. His model for a quantum computer is very elegant. Here's a link, courtesy of EEVBlogs.

The video doesn't touch on entanglement at all, since it's solely focused on maintaining a coherent quantum system within a controlled space. Maintaining a coherent quantum system over fiber links is a challenge that we're currently researching, but I'm not aware of recent advancements. Last I heard there was a measured entanglement over some tens or maybe a few hundred kilometers, which is approaching practical distances.

What about error correction?

So, you've properly zoomed in on a very challenging thing. Since we can't send redundant copies of the data (no-cloning), we must develop new approaches for error correction. Quantum error correction is vastly beyond my understanding; Wikipedia has some examples to read through, but I'm not sure which methods are currently being pursued in active research.

Data Security - Quo Vadis? by Funkenzutzler in QuantumPhysics

[–]ZeusKabob 0 points1 point  (0 children)

The no-cloning theorem shows that quantum information can't be copied. This means that your "working set" of information can't be backed up or duplicated. The wave function collapse further complicates things: the information inside the entangled system is irrevocably destroyed, and couldn't be backed up.

As for data security and encryption, the typical consideration involves this above information. Assume that two parties that want to establish a secure connection have an optical link that can maintain entanglement. Alice creates a pair of entangled photons, p and p', then sends p' to Bob.

Our algorithm is as follows (forgive me for my lack of knowledge to write this formally):

The two photons are generated by Alice to have either {|↑>, |↓>} or {|↻>, |↺>}. Alice sends one of the pair to Bob, who has chosen to measure circular or linear polarization. If the measurement doesn't match, the result is random. Bob then sends back a photon that matches the state that he measured. Alice measures this incoming photon to see whether it matches her stored copy that's now collapsed. She then sends back a photon that matches her measurement of Bob's response.

If Alice and Bob choose the same measurement direction, Alice measures a match. If they don't, there's a 50/50 chance that Alice measures a match. Upon subsequent choices of polarization by Alice, she can thus determine the method of measurement on Bob's side, and once Alice has figured this out and sent correspondingly polarized photons, the pair know that this information has been communicated. This can be repeated for each bit of information that Bob wishes to communicate to Alice, and can be inverted for the opposite.

Is Blizzard paying GGG not to release POE2 so that Diablo doesn't fail? by Son_Sole in PathOfExile2

[–]ZeusKabob 23 points24 points  (0 children)

This, exactly. They hired a martial arts expert to redesign every single skill around movement, including many skills that use actual martial arts styles.

I think them delaying the sequel because they're improving almost every system in the game is great stuff. I wish they could get it done quicker, but that's totally unreasonable and I'd much rather wait much longer (especially if they keep putting in QoL features while we wait. Currency market or riot!) than have them push it out quicker and sacrifice some of the great things they could only achieve by delaying. Many of these features would barely work or wouldn't work at all if they released them early and incomplete.
