Imagine you sit down and pick up your favorite book. You look at the image on the front cover, run your fingers across the smooth book sleeve, and smell that familiar book smell as you flick through the pages. To you, the book is made up of a range of sensory appearances.

But you also expect the book has its own independent existence behind those appearances. So when you put the book down on the coffee table and walk into the kitchen, or leave your house to go to work, you expect the book still looks, feels, and smells just as it did when you were holding it.

Expecting objects to have their own independent existence – independent of us, and any other objects – is actually a deep-seated assumption we make about the world. This assumption has its origin in the scientific revolution of the 17th century and is part of what we call the mechanistic worldview. According to this view, the world is like a giant clockwork machine whose parts are governed by set laws of motion.

This view of the world is responsible for much of our scientific advancement since the 17th century. But as Italian physicist Carlo Rovelli argues in his new book Helgoland, quantum theory – the physical theory that describes the universe at the smallest scales – almost certainly shows this worldview to be false. Instead, Rovelli argues we should adopt a “relational” worldview.

What does it mean to be relational?

During the scientific revolution, the English physics pioneer Isaac Newton and his German counterpart Gottfried Leibniz disagreed on the nature of space and time.

Newton claimed space and time acted like a “container” for the contents of the universe. That is, if we could remove the contents of the universe – all the planets, stars, and galaxies – we would be left with empty space and time. This is the “absolute” view of space and time.

Leibniz, on the other hand, claimed that space and time were nothing more than the sum total of distances and durations between all the objects and events of the world. If we removed the contents of the universe, we would remove space and time also. This is the “relational” view of space and time: they are only the spatial and temporal relations between objects and events. The relational view of space and time was a key inspiration for Einstein when he developed general relativity.

Rovelli makes use of this idea to understand quantum mechanics. He claims the objects of quantum theory, such as a photon, electron, or other fundamental particles, are nothing more than the properties they exhibit when interacting with – in relation to – other objects.

These properties of a quantum object are determined through experiments and include things like the object’s position, momentum, and energy. Together they make up an object’s state.

According to Rovelli’s relational interpretation, these properties are all there is to the object: there is no underlying individual substance that “has” the properties.

So how does this help us understand quantum theory?

Consider the well-known quantum puzzle of Schrödinger’s cat. We put a cat in a box with some lethal agent (like a vial of poison gas) triggered by a quantum process (like the decay of a radioactive atom), and we close the lid.

The quantum process is a chance event. There is no way to predict it, but we can describe it in a way that tells us the different chances of the atom decaying or not in some period of time. Because the decay will trigger the opening of the vial of poison gas and hence the death of the cat, the cat’s life or death is also a purely chance event.

According to orthodox quantum theory, the cat is neither dead nor alive until we open the box and observe the system. A puzzle remains concerning what it would be like for the cat, exactly, to be neither dead nor alive.

But according to the relational interpretation, the state of any system is always in relation to some other system. So the quantum process in the box might have an indefinite outcome in relation to us, but have a definite outcome for the cat.

So it is perfectly reasonable for the cat to be neither dead nor alive for us, and at the same time to be definitely dead or alive itself. One fact of the matter is real for us, and one fact of the matter is real for the cat. When we open the box, the state of the cat becomes definite for us, but the cat was never in an indefinite state for itself.

In the relational interpretation, there is no global, “God’s eye” view of reality.

What does this tell us about reality?

Rovelli argues that, since our world is ultimately quantum, we should heed these lessons. In particular, objects such as your favorite book may only have their properties in relation to other objects, including you.

Thankfully, that also includes all other objects, such as your coffee table. So when you do go to work, your favorite book continues to appear is it does when you were holding it. Even so, this is a dramatic rethinking of the nature of reality.

On this view, the world is an intricate web of interrelations, such that objects no longer have their own individual existence independent from other objects – like an endless game of quantum mirrors. Moreover, there may well be no independent “metaphysical” substance constituting our reality that underlies this web.

As Rovelli puts it:

We are nothing but images of images. Reality, including ourselves, is nothing but a thin and fragile veil, beyond which … there is nothing.The Conversation

Amazon’s best MacBook Pro deals of 2021 are available right now

Published

on

Are you looking for the fastest and most responsive experience possible on a laptop computer? You don’t need to spend a small fortune on a custom gaming machine with a gazillion gigabits of RAM. All you need is a new Apple notebook with Apple’s incredible M1 chip. And prices actually start much lower than you might think! That’s especially true for Apple’s Pro-grade M1 laptop. As a matter of fact, Amazon’s best MacBook Pro deals of 2021 are happening right now!

2020 Apple MacBook Pro with Apple M1 Chip (256GB) List Price:$1,299.00 Price:$1,099.99 You Save:$199.01 (15%) Buy Now Available from Amazon, BGR may receive a commission

The latest-generation M1 MacBook Air is Apple’s most affordable laptop you can get with the new M1 chipset. As if you don’t already know, Apple’s M1 is the SoC that’s making all kinds of waves right now. This entry-level Apple laptop is still powerful enough to computer crush rival Windows laptops that cost twice as much. And that’s especially true while Amazon is discounting the MacBook Air by up to $150.

Best MacBook Pro deals

Apple’s new Air laptop is lightning-fast indeed, but there’s another M1-powered Apple notebook that’s even more powerful. If you want the best of the best, you’re likely eying a brand new Apple M1 MacBook Pro instead of the Air. If that’s the case, we have some fantastic news: Now is the time to pull the trigger because Amazon is offering all-time low prices on both the 256GB model and the 512GB version, with $200 discounts on either size!

Searching for the fastest and most powerful Apple computers ever made? You now have four models to choose from. The new Mac mini is one, plus the new MacBook Air, and 13-inch MacBook Pro. And now, the new M1 iMac has finally been released (plus, it’s $50 off at Amazon!). These computers are all insanely powerful, and they’re all very new to Apple’s lineup. Despite how new they are though, Amazon already has some remarkably deep discounts.

Apple’s new Mac mini is the only M1-powered desktop that isn’t an all-in-one model. It’s so affordable, especially considering the fact that it crushes Windows PCs that cost twice as much. The same can be said of the MacBook Air, which is also on sale with discounts up to $150. But it should go without saying that the most exciting new M1-powered computer is the M1 MacBook Pro. And Amazon just slashed this incredible laptop to its lowest price ever.

The M1 MacBook Pro was between $50 and $60 off ahead of the holidays last year. Procrastination doesn’t often off, but this time around you’ll be very glad that you missed those deals. Head over to Amazon today and you’ll find that the 13-inch MacBook Pro with 256GB of SSD storage is $200 off. And if you want to bump your storage space up to 512GB you’ll still save a whopping $200!

Both of those deals are all-time low prices for Apple’s new M1 MacBook Pro models. But the bad news is we have no idea how much longer Amazon’s awesome sale will last. In other words, hurry up or you could miss out!

HBO Max free episodes are available right now to anyone

Published

on

Over the last few years, the number of streaming services on the market has increased at an alarming pace. Netflix, Hulu, Amazon Prime Video, Peacock, Paramount+, Disney+, HBO Max, and more are all competing for your time and money. But there are only so many hours in a day and dollars in our bank accounts. It’s a fierce competition, which is why every service is constantly finding new ways to reel in subscribers. To that point, HBO announced this week that episodes from some of the biggest shows on HBO Max will be free to watch for non-subscribers.

Today’s Top Deal Fire TV Stick 4K just got a rare 20% discount — don’t miss out! List Price:$49.99 Price:$39.99 You Save:$10.00 (20%) Buy Now Available from Amazon, BGR may receive a commission Available from Amazon BGR may receive a commission

If you’re curious about the HBO Max library, this is a great way to get a sneak peek before spending any money. HBO says the collection will initially include 13 episodes of HBO and Max Originals. New titles will rotate in and out of the collection periodically. Here are all of the pilot episodes that HBO says you can watch for free without a subscription:

With that said, when I visit the HBO Max free episodes hub, I see far more than what is listed above. Beyond those shows, I also see The Nevers, Mare of Easttown, The Undoing, Insecure, I May Destroy You, and Gossip Girl, to name a few. Perhaps those were already part of a separate promotion.

How to watch HBO Max free episodes

There are a number of ways to watch the free episodes on HBO Max. In addition to clicking on the link above in your browser, you can also access the free episodes on all of HBO Max’s device partners. This includes Fire TV, Android TV, Android, Apple TV, Chromecast, iOS, LG, PlayStation, Roku, Samsung, and Xbox. Basically, if you have the app, you can watch the free episodes.

Signing up for HBO Max

If the company’s gambit works, these free episodes might convince you to subscribe to HBO Max. If you’re a movie buff, you might want to take advantage of the ad-free tier for $14.99 a month. For the rest of the year, Warner Bros. Pictures movies will premiere in theaters and on HBO Max simultaneously. If you’re not interested in watching The Matrix 4 or Dune at home, you might prefer the cheaper tier, which costs $9.99 a month, but includes ads.

Windows 365 trials are now locked because everyone’s swarming to try it

Published

on

Microsoft brought Windows 10 to the iPad a few weeks ago, in what seemed like an extraordinary feat. However, you don’t actually get to install Windows on the iPad, and Apple will never allow that. But you can run the full Windows 10 experience on any internet-connected device that supports an internet browser. That’s because Windows 365 runs in the cloud, allowing businesses to offer their customers virtual Cloud PCs. Admins can customize these cloud computers in real-time, offering the kind of upgrades and downgrades that aren’t possible with real computers. Microsoft made Windows 365 available to businesses earlier this week, and it didn’t take long for the new Windows experience to sell out. Microsoft confirmed as much on social media, noting that the Windows 365 trial is locked for the time being.

It might seem impossible for a cloud service to sell out, but Microsoft ran out of cloud capacity to meet the massive demand. Brand new devices routinely sell out as companies hurry to mass-produce more units. But with a device in the cloud, the buyer doesn’t interact with a physical device. Microsoft could theoretically offer infinite Windows 365 virtual computers. But, in practice, that’s impossible.

Microsoft needs to have the cloud infrastructure in place to support all these concurrent Windows 365 sessions. And the company has run out of capacity less than two days after making Windows 365 available to businesses.

How Windows 365 works

Users added to a Windows 365 trial subscription will consume the virtual PC resources allotted to them. Admins can configure only certain key aspects of a Cloud PC, including CPU, RAM, and storage. They can add and remove resources as needed. They can remove people as well.

That’s a great type of Windows product that some businesses might find very useful. Rather than buying and maintaining new hardware for employees, some companies might want to deploy fleets of virtual Cloud PCs. Each employee gets their unique Cloud PC that’s hooked up to fast internet. And they can access their Windows 365 PC from any device that can connect to the internet. Hence, running the full Windows 10 experience on iPad is now possible.

Best of all, the user’s hardware will not impact Windows 365 performance. The Cloud PC experience is streamed to any internet-connected device. It’s the internet connection that matters here, not how powerful the user’s personal computer is.

Microsoft paused the trial

Microsoft did not disclose full pricing details for Windows 365 in mid-July when it announced the service. But the company opened the trial on August 3rd, revealing that Cloud PC rentals start at $20 per user per month. The cheapest Cloud PC features one CPU, 2GB of RAM, and 64GB of storage. The price goes up to $24 per month if you don’t own a Windows 10 Professional license.

That’s a great starting price, but it’s only available to businesses. Regular users who dream of a full-fledged Windows PC in the cloud can’t get on Windows 365. The best part of the service is that businesses get to try it for free for two months. That helps explain why Microsoft sold out all its Windows 365 trial “units.”

Microsoft confirmed everything on Twitter. Businesses that weren’t sure whether or not to get on the Windows 365 trial a few days ago will now have to wait. They can sign up to be notified when cloud resources become available.
