Why hurricanes hardly ever hit Europe

Standard

You don’t have to live far inland to avoid hurricanes. Just move to Europe. It rarely sees full-on hurricanes. But that may soon change. Following is a transcript of the video.

Europe hasn’t had a hurricane reach its shore in over 50 years. Now don’t get the wrong idea. Hurricane season still brings a hefty dose of wind and rain. But Europe has something that North America doesn’t, when it comes to protection against hurricanes. Location.

Hurricanes usually form off the coast of West Africa, where warm water near the Equator and high humidity create columns of rapidly rising rotating air. It’s the perfect recipe for a storm. Now the more warm, moist air that the system picks up, the stronger it becomes. That’s why a tropical storms can quickly grow into a full on hurricane as it marches across the Atlantic. Now normally hurricanes are propelled on a westward track by the trade winds, caused by the Earth’s rotation. That’s why Europe as well as the West Coast of the US, rarely experience full on hurricanes. But that’s not the whole story.

After all, since the year 2000, remnants of around 30 hurricanes have reached Europe. For comparison, Florida has seen 79 real hurricanes over the same time frame. By the time these remnants make landfall, they’ve went from a hurricane force, to a tropical storm or weaker. And that’s where Europe’s location comes into play. In order for a hurricane to head towards Europe, something crucial has to happen. It has to travel really far North by about 200 miles. Once a storm system reaches 30 degrees north, it encounters the subtropical jet stream. Which moves in the opposite direction of the trade winds. And therefore, blows the storm East But because the storm is now farther North, the waters underneath are colder by up to about five to 10 degrees Celsius. Which means less energy available to feed the storm. And as a result, it starts to die down by the time it’s headed for Europe. Even though it’s no longer a hurricane, it still packs a punch when it hits shore. In fact, most of these hurricane remnants will combine with other nearby cyclones and weather fronts, that create high winds and rain that mainly hit Ireland and Great Britain. But have been known to reach as far as Greece or even farther in Northern Russia. Typical damages include power outages, flooding, and occasionally casualties. Most recently the remnants of Hurricane Ophelia made landfall in Ireland and Scotland in 2017. About 50,000 households in Northern Ireland lost power. Three deaths were reported and downed trees closed many of the public roads and highways. This was the worst storm that Ireland had seen in 50 years. And it may be a sign of what’s to come.

As global surface temperatures rise, it will also increase the sea surface temperatures in the Northern Atlantic. Which researchers estimate could contribute to an increase in the number of hurricane force storms that reach Europe. Some experts predict that by the end of the 21st century, Europe could experience, on average, 13 powerful storms each year during hurricane season. Compared to the two per year it sees now.

Stephen Hawking’s last paper on black holes is now online

Standard

Stephen Hawking never stopped trying to unravel the mysteries surrounding black holes — in fact, he was still working to solve one of them shortly before his death. Now, his last research paper on the subject is finally available online through pre-publication website ArXiV, thanks to his co-authors from Cambridge and Harvard. It’s entitled Black Hole Entropy and Soft Hair, and it tackles the black hole paradox. According to Hawking’s co-author Malcolm Perry, the paradox “is perhaps the most puzzling problem in fundamental theoretical physics today” and was the center of the late physicist’s life for decades.

The information paradox arose from Hawking’s theoretical argument back in the 1970s that black holes have a temperature. As such, they’re bound to evaporate over time until there’s nothing left, releasing energy now called the “Hawking Radiation.” See, it’s believed that when an object enters a black hole, its information gets preserved on its surface forever even if it vanishes from sight. If a black hole evaporates, though, then so will that information. That creates a paradox, because according to the rules of quantum physics, information can never be destroyed.

The new paper shows how that information can be preserved by photons called “soft hair” surrounding the edge of black hole, which you might know as the event horizon. According to Hawking, Perry, Andrew Strominger and Sasha Haco, a black hole’s temperature changes when you throw an object (say, a planet’s atoms) into it. The hotter it gets, the more its entropy (its internal disorder) rises. That entropy is what’s preserved in a black hole’s soft hair.

Perry said he called Hawking a few days before he passed away to discuss their work. “It was very difficult for Stephen to communicate and I was put on a loudspeaker to explain where we had got to. When I explained it, he simply produced an enormous smile. I told him we’d got somewhere. He knew the final result,” he told The Guardian. The scientists admit that there’s a lot of work to be done, though: “It’s a step on the way, but it is definitely not the entire answer,” Perry said. “We have slightly fewer puzzles than we had before, but there are definitely some perplexing issues left.”

You can read the paper in full in its pre-published state. Earlier this year, Hawking’s last paper on the multiverse theory was also published in the Journal of High Energy Physics, in case that’s more up your alley.

Fake a $30k pro video controller with an APC40 or Beatstep and Davinci Resolve

Standard


We’re living in an age of video and motion graphics. But now not only can you get a free license of Davinci Resolve to use pro-level tools, but this hack will let you make a standard music controller do a convincing impression of a $30,000 controller. Finally, visuals get as easily hands-on as music.

The Tacyhon Post has a bunch of excellent tools for users of Davinci Resolve. (Resolve is the editor / motion graphics / post tool from Blackmagic. It’s a pro-grade tool, but you can use a free license.) But most intriguing are controller mappings for the Akai APC40 and original Arturia Beatstep. If you don’t have an APC40 already, for instance, that’s an inexpensive used buy. (And maybe this will inspired other mappings, too.)

The APC mapping is the most interesting. And it’s ridiculous how much it does. Suddenly color grading, shapes and motion, tracking and all the editing functions are tangible controls. THe developer has also added in mappings for Resolve FX. And it’s updated for the latest version, Resolve 15, released this summer.

Watch:

The Beatstep version is pretty cool, as well, with similar functionality to the APC. This isn’t the Beatstep Pro but the “vintage” Beatstep. Unlike the APC, that controller hasn’t had quite the staying power on the music side – the Pro version was much better. But that means it’s even better to repurpose it for video, and of course then you have an effective mobile solution.

If you’re the sort of person to drop 30 grand on the actual controller, this probably isn’t for you. But what it does is to liberate all those workflows for the rest of us – to make them physical again. The APC is uniquely suited to the task because of a convenient layout of buttons and encoders.

I’m definitely dusting off an APC40 and a forgotten Beatstep to try this out. Maybe if enough of us buy a license, it’ll prompt the developer to try other hardware, too.

Super custom edition by the script developer, with some hardware hacks and one-off paint job. Want.

Meanwhile, where this really gets fun is with this gorgeous custom paint job. DIY musicians get to be the envy of all those studio video people.

How Fast You Can Realistically Build Natural, Drug-Free Muscle? Here’s Your Answer.

Standard


How To Build Muscle Naturally

Photo by John Fornander on Unsplash

As a former 103 pound skinny runt I wanted nothing more than to build muscle. I figured more strength and muscle would help me in sports and more importantly, to get laid.

Unfortunately, I fell prey the same misinformation you probably see today.

“Add an inch to your arms this week!”

“Add ten pounds of mass in BulkTober!”

Whatever the marketing hype, I bought it…along with the supplements and miracle workouts programs sponsoring the overhyped programs. Chances are, you’ll have the same experience.

Realistic Muscle Building Expectations

Before setting any goal, you must know what’s physically possible.

For example, I’m 5’9”.  It’s an unrealistic expectation that I can make a living playing left tackle and protecting Aaron Rodgers blindside.

Just as I can’t expect to make a living playing left tackle, the average bro can’t expect to eat, train, and look like a bodybuilder.

Further, for most guys who want to look bigger, they’d be best served by getting leaner first. Getting leaner-10-12% where you can see some abs–will show more definition through your chest, arms, and back. Plus, the leaner you are, the less body fat you’ll store when bulking up.

Consider getting leaner first before trying to build muscle.

The Scientific Models of Muscle Growth

The Lyle McDonald Genetic Muscular Potential Model is the golden standard when it comes to determining “how much muscle you can build.”

For starters, this model is built for natural, drug-free guys. Second, this is the maximum potential–meaning if you do everything right, this is what you can expect. Most guys don’t do everything right, whether they’re not eating enough, not training correctly, or skipping on sleep.

What does this mean?

Building muscle is a slow process. Agonizingly slow, to be exact. Most guys scoff at the idea of only adding one or two pounds of muscle per month, trade in their beer money for weight gainer shakes, and add up building their FUPA faster than their biceps.

Bad idea.

When it comes to building muscle, play the long game. The longer you lift and train correctly, the longer it’s going to take, likely capping your muscle growth at 40-50 pounds, total.

As you progress, it gets exponentially harder to build lean muscle.

For example, a 30-year-old or 40-year-old silver-back bro will struggle to gain as fast as an 18-year-old male with the testosterone of a raging bull.

Realistic Muscle Building In Action

Let me tell you about David.

David is a 21-year-old college student. He lifted weights in high school and as a freshman in college but fell off every few weeks. David would rather play Call of Duty, drink cheap beer, and chase girls. Not a sad life too different from my college days.

Unfortunately, girls don’t often date quiet, timid guys who resemble their cute nephew.

David grew sick of the same old same old and decided to build muscle once and for all.

At 140 pounds, David follows a workout plan based on getting stronger in the gym with exercises like squats, deadlifts, rows, and bench presses. He’s training four days per week and tracking his workouts.

He’ll no longer eat “a lot.”

To find how many calories he needs to eat, he took his bodyweight (pounds) x18.

140x 18= 2520 calories.

He’s eating 1g of protein per pound, (140g) and plenty of carbs and fats to fill the rest of his diet.

He’s tracking his diet, drinking less beer, and even sleeping eight hours per night.

Here’s what he can expect.

Year One: Beginner

Woohoo! David built a decent amount of lean muscle. Here’s how it breaks down:

140lbs x .0125 (rate of total body weight per month) = 1.75 pounds per month = 21 pounds per year.

David gained nearly 2 pounds of lean muscle per month and now weighs 161 pounds. Goodbye, little t-shirts and hello, mediums.

 

Year Two: Intermediate

For the first time, David started to hit a wall with his workouts. Luckily, he tweaked his routine by working with me as his online coach (shameless plug, I know; did I mention I now have a mortgage, a beautiful lady to please and a dog to feed?) David started to add lean muscle again.

161 lbs X .0075 (rate of total body weight per month) = 1.2 pounds per month or 14 pounds in a year. David is still gaining at an impressive rate.

David gained about a pound per muscle and now weighs 175 pounds. He’s lean with a few abs showing and appears much bigger than he is. David deadlifts 405 lbs and looks better than 90% of guys in the gym.

As to whether his dating life is improving, I leave that to your imagination.

Year Three: STILL Intermediate

David has learned a lot. He might not be a gym Jedi, but he’s every bit a Han Solo.

He knows how to make subtle adjustments to his training. He tracks his workouts and “feels” when he needs to push harder or dial back. He’s in the zone and pushing his body to the max.

175 lbs x 0.0037 (rate of total body weight per month) = 0.65 pounds of muscle per month, or 7.7 pounds in a year.

David gained almost eight pounds in his third year and now weighs 183 pounds.

His strength gains slowed down, so he added more training volume to focus on building muscle. Right now, he’s at a level most folks won’t ever reach in the gym.

How did David do it?

Well, he’s been consistent.

David can continue making progress, but the process will be slow. He’s creeping towards his genetic limit for size and strength. He might gain a few pounds per year, but he’s not piling on 30 pounds of new muscle like a newb.

The Journey

After a few years of solid training, your progress will slow to a trickle. No biggie, it’s part of the game when you’re no longer makin’ newbie gains.

Again, your reaction to slower progress is key. Don’t try every method under the sun and end up with information overload,  like most lifters. Instead, reconsider down on your expectations and review your progress.

Are you willing to dedicate every aspect of your life for bigger arms or a more symmetrical body?

If not, consider continuing on your path and understanding you’ll still make progress, but it’s going to be a journey.

Remember most guys can build around 40-50 pounds of lean mass.

Gaining more than the aforementioned 40-50 pounds requires an elite level of discipline (like competitive bodybuilders) and potentially, a good pharmacist. Not here to judge in either way, but facts are facts.

The Takeaway

You can gain 1-2 pounds of lean muscle as a beginner and gradually less; .2 – .5 lbs per month after. The process is slow when looking forward, but well worth the journey.

Self-repairing material plucks carbon from the air

Standard



Strano et. al.

Scientists might have a particularly clever way to help the environment: they’ve developed a material that can not only heal itself, but could reduce CO2 levels in the process. The substance uses its combination of a gel-like polymer with chloroplasts (cell elements that handle photosynthesis in plants) to grow by snatching carbon from the air after exposure to light. If you cracked or scratched an already-solidified piece of this material, the newly exposed sides would promptly expand and fill the gap without requiring heat, ultraviolet light or other special reactions like you see with existing self-healing products.

Researchers have isolated chloroplasts before this, but these organic components tend to stop working a few hours after removal from a plant. The team made them more practical by significantly extending their useful lifespan.

There’s more work to be done, such as replacing the chloroplasts with artificial catalysts that could achieve a similar effect. The potential applications are already clear, however. You could use the polymer as a building material that fixes itself while countering excessive CO2 emissions. It might function as a coating for other products, too. And it could even be economical — construction crews could ship the material in liquid form and make panels out of it at the building site. Urban sprawl would still be a problem after this, but it might have its upsides for the planet.

Palm returns as an ‘ultra-mobile’ smartphone

Standard

I shared images I shot of the Palm device with a few co-workers ahead of this morning’s unveiling, and they were downright giddy. The new “ultra-mobile” device (a term us old people used to use to refer to something closer to a netbook) is a hard thing to contextualize without a picture, so I took a bunch, and many of my oft-jaded co-workers fell for the thing immediately.

The device, which is designed to split the difference between a smartphone and a smartwatch, is admittedly adorable. The startup behind the product employs designs with some impressive credentials, from Samsung to Frog Design.

Really, the device most obviously resembles an iPhone, shrunk down to a 3.3-inch display. The first iPhone, incidentally, had a 3.5-inch screen — though a lot has been done in the intervening 11 years to jam that kind of real estate into a far smaller footprint. And this device, fittingly, fits comfortably in the Palm of your hand.

But adorableness is hardly enough to convince a large swath of the public to shell out $349 for a product category they didn’t know they needed in their life until this morning. There are a number of issues. For one thing, this is a Verizon exclusive. Sure, our parent company’s parent company has a lot of subscribers, but you’re already writing off a number of potential buyers with the fact that you need an existing VZW plan to tack the Palm onto. Oh, and that will run you an additional $10 a month.

[Note: I did not take this photo of Steph.]

I’m sure you’re already imagining the ways this thing will fit into your life. If not, Palm investor, accessory designer and Splash Brother Stephen Curry is happy to help you. The Warrior all-star has been incorporating the product into his off-season workouts, and certainly there’s something to be said for the much smaller form factor when it comes to strapping it to your arm for NBA workouts.

For the rest of us, perhaps the reborn Palm represents freedom from being tethered to our six-inch smartphones. Granted, it’s still a smartphone of sorts, but it’s a start. And the device can help you get a lot more done than your average smartwatch — though I speak from experience when I say it’s going to take a lot of practice to get used to typing on that tiny screen again.

The Palm runs Android (8.1), naturally. Though the company has created a custom skin that forgoes the desktop and takes you right into the app tray. From there, you can reorder your apps based on preference. And yes, unlike Wear OS, they run as their full versions here.

The device is IP68 water-resistant and sports an 800mAh battery — not big, but then, neither is the screen, so they ought to even each other out. Palm rates it as “All Day.” Inside, you also get 3GB of RAM, 32GB of storage and a Snapdragon 435. Those are bad smartphone specs, but perhaps good specs as far as “ultra-mobiles” go? Hard to say. The category didn’t really exist until right now.

The newly reborn Palm created the device with help from supplier TCL. Unlike TCL’s BlackBerry deal, however, the startup owns the exclusive rights to the once-mighty Palm name and operates independently of the massive Chinese phone maker.

Cute? Check. Interesting? Double check. Ready to disrupt the industry? The jury is definitely still out on that one.

3 Myths About Algorithmic Trading

3 Myths About Algorithmic Trading

By Nitesh Khandelwal

Algorithmic Trading is often confused with similar concepts and terminologies like quantitative trading, HFT and Automated trading, here are few of them that everyone needs to have clarity about

With the emergence of new technologies, it becomes essential to have clarity of the concepts related to it, which may otherwise cause unpardonable mistakes resulting in losses. Algorithmic Trading is one such domain which is witnessing a rapid growth and hence is surrounded by many myths arising due to misinformation and lack of clarity. Among the few misconceptions which I came across, these are few of them which I feel everyone needs to have clarity about.

Algorithmic Trading is the same as Quantitative Trading, High Frequency Trading (HFT) and Automated Trading

Algorithmic Trading is often confused with similar concepts and terminologies like quantitative trading, HFT and Automated trading. Though these are quite related, but are different from each other. Let us understand these differences by explaining what each term means.

Algorithmic Trading –  Algorithmic Trading is the process of converting a trading strategy into an algorithm or computer code, and checking whether the strategy provides us with good returns by performing backtesting on historical data.

Quantitative Trading – Quantitative trading involves using advanced mathematical and statistical computations along with quantitative analysis to devise trading strategies. This can then be executed manually or in an automated fashion, depending on the strategy (and the strategist!)

Automated Trading – It is automating the overall process of order executions like buying or selling and would often have portfolio & risk management automated as well..

HFT (High-Frequency) Trading – High Frequency Trading involves executing orders in an extremely short span of time, usually in a sub second, and targeting minuscule profit from each trade but doing a vast number of them overall. HFT is a subset of Algorithmic Trading and given the speed at which you’d need to send the orders, must be automated. Interestingly, most of the HFT strategies, except for plain vanilla arbitrage, are quite quantitative in nature.

Retail traders are at a loss due to the use of colocation by High Frequency Traders

This is one of the most common myth regarding the use of colocation and stands completely incorrect as the High Frequency Traders do not compete with retail traders, rather they compete amongst themselves.

Colocation involves placing the servers of the HFT traders in close proximity to the exchange. Given that most of the markets are made (market making) by HFT desks, and since they target to collect few pennies on an average per trade, any sudden event/news can cause significant losses. Being in colocation facility ensures that they are able to update their orders to the fair price within a very short time. This ensures that they are able to offer much better quotes, resulting in significant saving in transaction cost for an average retail trader.  Effectively, it potentially benefits the retail traders as the bid-ask spread is reduced and they can execute their orders at a better price in general.

Individual traders can’t do Algorithmic Trading

As opposed to HFT which can’t be done by an individual trader, Algorithmic Trading can be done by individual traders in most major geographies globally. Algorithmic trading needn’t involve huge capital investments in infrastructure and technology, which is why it is an open domain for everyone to explore. What it requires is a trading idea or strategy converted into an algorithm or code and implemented. Many might be skeptical to try out Algorithmic Trading on their own in live markets for which backtesting, a process which involves testing the strategies on historical data, is of great benefit to ensure maximum efficiency of the trading strategy.

Now that you are familiar with these concepts and have gained clarity about these common myths, you can start exploring the field of Algorithmic trading and bust more such myths surrounding this topic.
