Some legacies that it has left in modern society are: safe buildings, x-rays, the microwave oven, the GPS location system, laser technology, ultrasound, magnetic resonance and radiotherapy. With our collection you can enjoy the following subtopics: Basic physics, advanced, applied, acoustics, particle physics, electromagnetism, fluid mechanics, among others.Īdvances in physics have made life easier for us today. Thermodynamics: Studies energy and heat, as well as the systems through which they are preserved and transmitted.Įlectromagnetism: Studies energy in matter and space.įluid Mechanics: Studies the functioning or dynamics of liquid fluids and gases. Let’s describe a little bit some of them:Īcoustics: Study the nature of sound, where it comes from, how it spreads, etc. As you see, it is a science that encompasses many specialties. Physics is divided into several branches, among which are: acoustics, electromagnetism, mechanics, fluid mechanics, optics, thermodynamics, cosmology, quantum, among others. Similarly, it studies the interaction between these elements, resulting in turn in other phenomena such as gravity, electromagnetism and nuclear forces. Throughout history, physics has explained phenomena such as time, space, matter, energy, movement, light and sound. The way to materialize the findings occurs through systematic study, using the scientific method for hypothesis testing. In fact, it explains everything that surrounds us, from the smallest to the most immense from the indivisible particles to the planets. Physics studies the phenomena of the universe and the laws that govern it. This also brought consequences such as the phenomenon of encyclopedism, with the division of knowledge that prevails until today. ![]() ![]() This was so until the arrival of the Enlightenment and the Industrial Revolution, a historical moment in which the sciences were separated as disciplines independent from philosophy. In its beginnings, physics was part of philosophy, more specifically during the classical period. ![]() We have done it for you and we hope that the list of works on physics will be really useful for you. #Physics made easy pdf pdf#We provide you with books on physics in PDF format to help you in your search so you don’t have to spend time organizing the material.

Good hair day by Wolf Cut With Wispy Bangs #WOLF CUT FEMALE THIN HAIR HOW TO#Keep scrolling for five of our favorite wolf cut inspiration photos-plus a few tips on how to achieve these looks for yourself. Looking for a little inspo to style your existing (or future!) wolf haircut? We’ve got you. This multi-benefit formula completes any style with light hold, texture, and lasting volume. She adds, “My favorite product to tame any frizz at home is the Matrix Total Results Miracle Creator Multi-Benefit Treatment Spray.”įor adding volume and texture, we recommend Matrix Miss Mess Dry Texturizing Spray. “, my top tip would be to make sure you’re prepared on how exactly you want your haircut done and specify whether you want more or less layers and volume,” says Spellman. In addition to texturizing and volumizing hairspray, you should also have products in your routine that can tackle frizz. Styling the wolf cut means leaning into texture, not shying away from volume, and embracing that carefree essence. Think of it as a party all over versus just in the front.” “Mullets tend to be much tighter and more cropped at the top, while the wolf cut layers blend more seamlessly. “The difference between the wolf and the mullet is the softness of the look,” Spellman explains. ![]() While the wolf cut definitely has similar features to a mullet, the two aren’t quite the same. Good hair day by Is a wolf cut the same as a mullet? (However, a certain ‘80s band officially coined the term in one of their famous songs). Partial credit also goes to the OG mullet, which surprisingly dates all the way back to ancient Greece. That said, if we want to get really technical, then inspiration for the wolf cut can be linked back to hairstylist Paul McGregor, who created that iconic shag on a certain award-winning actress. Just like the BB cream took about a decade to make its way West, so did the wolf cut. Several well-known K-Pop singers rocked the iconic shag-meets-mullet ‘do, creating a micro-surge in popularity. Though the wolf haircut is trending right now, it actually first popped up in South Korea in the mid-2000s. Good hair day by Who started the wolf cut hair trend? #WOLF CUT FEMALE THIN HAIR PROFESSIONAL#“Haircuts take a lot of professional training, therefore even if you have the best scissors in the game, you don’t have the experience like the pros,” says Spellman. Unless you’re a seasoned pro, we recommend saving your hair (and some tears) by scheduling a visit with your stylist. There’s a current TikTok trend where people are DIYing the wolf cut. However, if you have straight hair, you’ll probably want to use some hot tools and the right styling products to add texture and volume-two key facets of this trending style. She adds that there isn’t a specific hair type that should avoid a cut like this. It’s an extremely gender neutral style therefore all humans can spice up their look and feel their best.” You can make it wild, or chill it out keeping the length, volume, and wispy layers on point,” says Spellman. ![]() “The wolf cut is a mixture between the shag and mullet haircut. Rather, it’s the earthy and untamed nature of the cut that inspired its name. If you search for pictures of wolves, you’re probably not going to see a resemblance between the animal and the style itself. Keep scrolling for everything you need to know. To help you get a better picture of the wolf cut hair trend, including where it originated and how to style it, we tapped Sharon Spellman, hairstylist and Matrix brand ambassador.

The fact of the matter is that you can't please everyone. Streaming services are tricky to master for. A mastering compressor will decrease your dynamic range, so compensating for this during mixing is a good idea. So when mixing, focus on getting the best clarity, with a large dynamic range. This gives us a dynamic range of 12dB.Īfter mastering, your dynamic range should be between 10dB and 16dB. Say your loudest point is at -6dB, while your quietest moments are around -18dB. Going from quiet to loud increases energy, and makes music more impactful.ĭynamic range is the difference between your loudness peaks and troughs. A lot of emotion, and forward movement in music, is dictated by the level of dynamic range. These decisions very much depend on genre and intended output.Ī jazz track will be mixed and mastered quieter than a hard dubstep track would.ĭynamic range is a very important consideration when mixing and mastering. Mix engineers like Steve Albini have long been intentionally squashing their dynamic range with limiters, to create louder and punchier mixes. That being said, limiting isn't actually a bad thing in some cases. If your track mix is really hot (really loud), putting a limiter on the tail end of it, will leave a lot of unwanted clipping and digital distortion artefacts.Īdd to that a very compressed dynamic range, and your songs will start to sound like a mush of sounds, rather than a fully realized mix and master. Clarity is the sole reason we do any levelling, panning, stereo adjustments, compression etc.īy putting a limiter on your master bus, you're essentially reducing the dynamic range of your mix. Mixing is about clarity and balance across the board. Mixing, contrary to popular opinion, isn't about extracting as much loudness as you can from your track. ![]() Overusing limiters however, will reduce your dynamic range, while introducing clipping and other digital sound artefacts in your track. It's attractive, it's easy, you can mix how loud you want, and turn it down to proper levels with a limiter. One of the first things you'll learn as a mixing engineer is, don't cheat with a limiter on your master bus. That's the quick answer, but as usual, it's a bit more nuanced than that. If you want to send your mix off to get mastered, you should aim for around -6dB Peak, and anywhere from -23 dBFS RMS or LUFS to -18 dBFS RMS or LUFS average.

Technically, you can do two commands because one is for a single tap, while another is for a double tap. If you prefer, you can change it to trigger Siri or Google Assistant, start a timer or stopwatch, or start playing a Spotify or Apple Music playlist. Each side’s outer shell is a physical button, and by default, one controls play/pause, the other volume. The only custom choices available are in assigning controls to the buttons on the earbuds themselves. #BACKBEAT FIT 3200 FREE#Controls are good, however will need a little tweaking but compared to its similar priced competitors, Plantronics definitely have an advantage when it comes to audio quality, battery life, ease of setup/use and overall usage.Being Bluetooth-enabled, the BackBeat Fit 3100 paired pretty quickly the first time, and generally every time after that.īeyond basic Bluetooth, Plantronics has a free BackBeat app for iOS and Android, but don’t expect a myriad of options - there’s no EQ or deep customization. If you’re looking for a more immersive audio experience, the Plantronics BackBeat Fit 3200 is the model to go for and it’s great that Plantronics are making their products more smart friendly with elements such as access to the Google assistant and ability to tweak the audio quality. The call quality for both parties was good and even outside, the other person could hear us well. Furthermore, you can answer calls and even access your virtual assistants as well. #BACKBEAT FIT 3200 PLUS#This apps also allows you to swap which is your primary earbud, including controls such as one tap to play/pause or two to skip plus volume controls. You also have access to an app which allows you to tweak these earbuds, including audio presets. ![]() It is definitely an immersive experience, particularly with its element of noise-cancellation and decent bass, no matter what music genre you are listening to. #BACKBEAT FIT 3200 DRIVERS#Thanks to the its drivers with a frequency range of 20Hz – 20,000Hz, the Plantronics BackBeat Fit 3200 produced exceptionally clear audio with good mids and highs. However the only thing missing is USB-C charging and 2020 is the year of USB-C!įurthermore, they are a well-made product and the ear loops really allows you some great flexibility in terms of your workouts, whether doing burpees, running or even rock climbing… in other words, these will definitely stay in your ear and they are very comfortable. Charging is also done through the USB port and it even has a quick charge option of an additional 1.5 hours of charge in just 15 minutes. The earbuds boast 8 hours of charge with the ability of two additional charges thanks to its case which gives you an additional 16 hours. This means that they help in “dulling” background noise and allows you to concentrate on your workouts more thanks to the smooth audio experience. It also has an IP-57 rating that makes 3200’s sweat resistant and to some extent water proof if you’re working out in the rain.Ĭompared to the BackBeat Fit 3150, the audio quality is a little better but more importantly, they boast in-ear noise isolating silicone tips. #BACKBEAT FIT 3200 BLUETOOTH#As the packaging states, they are true wireless earbuds which use Bluetooth 5.0 to ensure a strong connection with no dropouts or interference and after using the Plantronics BackBeat Fit 3200 for almost a month, I can concur that this is the case. ![]() Having recently reviewed the BackBeat Fit 3150 ( review link), I had the chance to check out Plantronics BackBeat Fit 3200 that are considered the next model up. ![]() ![]() ![]() It’s a perk, but when a shadow that’s taking up a significant portion of the screen looks much worse, it’s time to prioritize. You can see the streaking and aliasing present on Agent 47’s back in the ray-traced image (below left), which isn’t present with ray tracing turned off.Īs my screenshots from Miami show in the section above, ray tracing renders shadows that otherwise wouldn’t be in the game. With ray tracing on, some shadows showed nasty interactions with the highly detailed surfaces in the game. Turn on the ray tracing switch, and those intentions are lost.Ĭhongqing was disappointing, but the Miami level was downright shocking. IO Interactive clearly designed this scene so that it was drenched in the neon glow of a Chinese city, which means bending the rules of how light behaves to achieve an artistic vision. It’s a case of expectation versus reality. The ray-traced image is certainly more realistic - a rain-soaked wall in an alley wouldn’t reflect lights that are a mile or more away - but does it look better? Not really. In the ray-traced image (above left), you can see the left wall doesn’t hold a reflection like the image without ray tracing. I was especially disappointed in the neon-dripped Chongqing level, where I expected ray tracing to shine the most. ![]() Hitman 3 wasn’t designed with full-on ray tracing in mind, which leads to some awkward scenes where turning ray tracing on actually makes the game look worse. Unfortunately, the pros of ray tracing in Hitman 3 are massively outweighed by the cons. There are some visual benefits to turning on ray tracing in Hitman 3, but the vanilla build offers much of the same experience, especially concerning details you’ll actually look at. #1440p hitman 2 images windowsThe windows on each hut (below) look much nicer from a distance with ray tracing turned on, but they have the exact same reflection when you get up close to them. In the Maldives, I found similar shifting to the default reflections. They look fantastic, but that wasn’t my experience through all of the levels I looked at (more on that in the next section). In this scene, ray tracing is helping the shadows more than anything else. Below, you can see how the middle and right images (ray tracing on and off, respectively) look identical despite the ray-traced reflection in the left image. Hitman 3 already uses screen-space reflections, and even with ray tracing turned on, it will default to these reflections when you’re up close. In many cases, you’re getting ray-traced reflections even without ray tracing turned on, which both the Maldives and Miami levels confirmed.įor the window in Miami, it showed the wonderful ray-traced reflections from a distance, but that reflection quickly shifted once I took a few steps toward the window. While playing, they’re hard to notice because Hitman 3 already has fantastic reflections and lighting. The issue is that these comparisons only hold up in one-for-one screenshots. ![]() I captured another example in the Miami level (below), where you can see the ticket booth window reflecting the people in line with the ray-traced version (left). You can see an example of that in the Maldives level from Hitman 2 below (ray tracing is on the left). I noticed the reflections most on semitransparent reflective surfaces (mostly glass), where ray tracing shows reflections that wouldn’t normally render. That’s not to say ray tracing isn’t doing anything, just that it’s not doing very much. If they weren’t side by side, I wouldn’t be able to tell you which one is using ray tracing, certainly. The ray-traced version (left) shows the beam that Agent 47 is climbing cast slightly more shadow, but these two scenes are almost identical. You can see an example of that from the Dubai level above. But after playing through several missions and capturing around 50 screenshots, it’s hard to see the benefit. #1440p hitman 2 images updateThe update brings ray-traced reflections and shadows, which you can toggle on individually. Hitman 3 has very little to gain from ray tracing, and spending some time with the new update only confirmed that for me. Hitman 3 is a reality check, especially if you think ray tracing is the be-all and end-all of graphics. Ray tracing can certainly make visuals more realistic, but in this game, it proves that adding ray tracing to all games isn’t necessary - especially when it tanks performance without adding much in terms of noticeable benefit. ![]() Now, eCommerce companies have fine-tuned the process, finding “just the right price” for bringing a customer and a particular product together. Prior to price-oriented algorithms, online sellers competed with one another by slashing prices and minimizing profits. The use of Machine Learning is broadening to include all aspects of eCommerce, the Internet, and technology. Machine Learning algorithms are transforming major portions of the economy, altering how everything from online product marketing to customized search engines, and from self-driving cars to advanced medical imaging. Although bagging is normally used with decision tree methods, it is adaptable to any type of Machine Learning method. Bootstrap aggregating, also referred to as bagging, is an “Ensemble meta-algorithm” for Machine Learning, created to promote the accuracy and stability of programs used in regression and statistical classification. Bootstrap Aggregating algorithms were the first effective Ensemble Learning algorithms. They are designed to help train “other” Machine Learning programs. Ensemble Learning algorithms act to combine the outputs from different Predictive Analytics models, and produce a “single” output.It is often used to provide “relevance” to search engine results. It can describe all predicted outcomes and predict the probability of each. A probabilistic model is meant to give a distribution of possible outcomes. One of this model’s advantages is that it returns both the prediction, and the degree of certainty. Probabilistic Models typically attempt to predict the best response by creating a model with a probability distribution.SVMs are good at recognizing facial images and handwriting. More precisely, regression analysis helps in understanding how “criterion variables” change in value, when one of the independent variables change, while other independent variables remain fixed. These algorithms analyze data, and are used for classification and for “regression analysis.” (Regression analysis uses statistics to estimate “the relationships among variables.”) It supports modeling and analyzing techniques using several variables, when the focus is on the relationship. Support Vector Machines (SVMs) are “supervised” learning models with appropriate learning algorithms.Deep Learning is ideal for working with Big Data, voice recognition, and conversational skills. The additional processing layers provide higher-level abstractions, offering better classifications and more accurate predictions. Interconnected “artificial” neurons are arranged in multiple processing layers (two is common with other Machine Learning systems). Neural networks attempt to imitate how the human brain works. Listed below are some of the basic categories and related areas: There are a variety of Machine Learning algorithms capable of assisting automated Data Modeling programs, and improving Data Management, eCommerce, and robotics. In the world of commerce “trend forecasting and analytics” rely on Machine Learning algorithms to anticipate shifts in purchasing behaviors, providing significantly better forecasts than had been done before the algorithm’s development. The Mars rover Curiosity uses a form of Machine Learning to traverse the Martian terrain, and there are plans to use the same algorithm for driverless cars. Machine Learning algorithms are trained with large amounts of data, allowing the “robot” to learn and anticipate problems and patterns. (For a primer in Machine Learning, see this article). USAGE BASED LIFING FULLThe full impact of Machine Learning is just starting to be felt, and may significantly alter the way products are created, and the way people earn a living. These algorithms find predictable, repeatable patterns that can be applied to eCommerce, Data Management, and new technologies such as driverless cars. The overarching practice of Machine Learning includes both robotics (dealing with the real world) and the processing of data (the computer’s equivalent of thinking). ![]() Machine Learning algorithms can predict patterns based on previous experiences. ![]() |
