The 100 Best Music Videos of 2019

You know why? Also, ” best music videos ” is a somewhat valuable search phrase that, over the course of an entire year, pays off with loads of clicks and, probably, some passive revenue from Google ads. But that’s a side of the business I don’t deal with, so perhaps I should shut my mouth and make content. Everyone lives to serve the algorithms now, so get on board or get off the internet!

While the nature of online video production and consumption may have changed, what’s stayed the same is plenty of artists and directors continue to collaborate on music videos that deserve your attention. Here are the finest the medium has to offer, so check back regularly or every day, just make sure you close and reopen your browser!

Gopal Erinjippurath October 29, Recent innovations in agile aerospace have created unique offerings in high cadence satellite imagery. While this is of immense interest to imagery analysts, a significant portion of GIS professionals and geo-data scientists work less with raster data AKA imagery and more with point and vector data. Over the past couple of years, we have been working on bringing computer vision and spatiotemporal analysis to market to enable access and data transformations on this rich imagery archive.

Dating of archeological and geological materials is an important task in the fields of history, anthropology, archeology, geology, paleontology, etc. Within the wide variety of such scientific sources of information, physical and chemical methods of dating play an essential role and, to a great extent, they share the same general methodologies which are applied in analytical chemistry.

The basis of the main physical and chemical methods of dating is discussed with particular attention to calibration and error estimation. We experience time based on our perception of events and our memory of the events in the past and associate time duration to repetitive events but our ability to comprehend duration remains ultimately subjective, biased by the conditions of our individual experience. Astronomical time is based on the repetition of astronomical phenomena.

Although these phenomena are not exactly repetitive in terms of contemporary atomic time scales, they are important because of their use in calendars as well as for observers on the Earth needing to determine the orientation of our planet in an inertial reference frame, namely, navigators, astronomers and geodesists [ 2 ]. In the field of physics, the concept of time was dominated by the Newtonian view of an absolute universal, homogeneous time inextricably following from the concept of absolute space.

In the Principia [ 3 ], Newton wrote:. The universal Newtonian time, flowing uniformly, whereas the material bodies experience different processes in an empty, absolute space, is one of the essential elements of the paradigm of classical mechanics. The Newtonian time still remains, probably, as an implicit conceptual background for the contemporary view of dating but the concept of time has been significantly revised in the relativistic theories and in quantum mechanics [ 4 , 5 ].

For our purposes, the relevant point to underline is that dating can be considered as a procedure for fixing a given phenomenon, the fabrication of an artifact, the minting of a coin, the death of an organism, on a standardized time scale, thus providing valuable information for historical, archeological, geological purposes, etc. This requires to have a clock, i. The zero setting, for instance the death of a living organism in radiocarbon dating, is the event defining the initiation of the time-counting process.

All dating procedures astronomical, biological, stylistic, etc.

Comet Neowise swept within Mercury’s orbit a week ago. Its close proximity to the sun caused dust and gas to burn off its surface and create an even bigger debris tail. Now the comet is headed our way, with closest approach in two weeks. Scientists involved in the mission said the comet is about 3 miles 5 kilometers across. Its nucleus is covered with sooty material dating back to the origin of our solar system 4. The comet will be visible around the world until mid-August, when it heads back toward the outer solar system.

While it’s visible with the naked eye in dark skies with little or no light pollution, binoculars are needed to see the long tail, according to NASA. NASA’s Bob Behnken shared a spectacular photo of the comet on social media late Thursday, showing central Asia in the background and the space station in the foreground. Open main navigation Live TV.

Earth’s Earliest Atmospheres

Neill glasgow. I study the manner in which Earth’s lithosphere is formed, deformed and recycled through geologic time using a mix of geochemical proxies, fieldwork and integration with geodynamic models. I have also been involved in the hunt for analogues for Earth’s earliest continental crust, identifying recycled crystal cargoes in magmatic systems and road-testing new geochemical discrimination diagrams.

Earth is the one known example of an inhabited planet and to current knowledge the likeliest site of the one known origin of life. If life began on Earth, as opposed to having migrated here, it would have done so after the Moon-forming impact. What took place before the Moon formed determined the bulk properties of the Earth and probably determined the overall compositions and sizes of its atmospheres and oceans. What took place afterward animated these materials.

One interesting consequence of the Moon-forming impact is that the mantle is devolatized, so that the volatiles subsequently fell out in a kind of condensation sequence. This ensures that the volatiles were concentrated toward the surface so that, for example, the oceans were likely salty from the start.

Dating: an analytical task

In autumn the Ion Beam Center of HZDR has expanded its measurement capability by another highly-sensitive analytical method, accelerator mass spectrometry AMS , which is used for the determination of long-lived radionuclides. In contrast to ordinary decay counting, the “impatient” scientists do not wait for the disintegration of a radioactive nucleus.

In fact, they determine the not-yet-decayed radionuclides by mass spectrometry, which is much more efficient. There is a main advantage of using a high-energy accelerator for mass spectrometry: The background and interfering signals, resulting from molecular ions and ions with similar masses e. Thus, AMS generally provides much lower detection limits in comparison to conventional mass spectrometry.

Our AMS system offers excellent measurement capabilities also for external users.

Years ago, my stepmother, who was then in her 70s, was planning to come over to our house from Falmouth for Thanksgiving dinner, and she called the day before to ask if it would be all right if she brought a friend — someone she had just met on match. We said of course, and then looked on in bemusement as she made out with her friend in front of the fireplace after dinner. Back in the day people met the old-fashioned way … through friends, at work, or in bars. But I wondered how seniors, in the age of match.

I started by asking a contributing writer for The Times, Abby Remer, if she had any experiences with online dating. Abby is a youthful 60 years old, blond and attractive. She is from New York and was divorced in , and while she was leery of online dating, she decided to give it a try. Abby decided to set some guidelines. She was looking for dates who were thoughtful. If she was sufficiently interested, things could progress to a cup of coffee.

There was the guy who tried to deep-throat kiss her at the end of their coffee date. There were the guys who misrepresented themselves with old pictures, there were the guys who turned out to be married. Abby ended up dating a few guys, but nothing serious came of it.

AMS is an ultra-sensitive analytical technique for measuring low levels of long-lived radionuclides and rare trace elements. At Purdue we have constructed a major national AMS facility centered around the Physics Department’s tandem electrostatic accelerator. We are using the accelerator to measure both man-made and cosmic-ray-produced radionuclides such as 10 Be half-life 1,, years , 14 C years , and 36 Cl , years in natural samples having isotopic abundances down to one part in 1×10 15 a thousand million million.

Arto Luttinen Ph. Jussi Heinonen M. Ilona Romu M. Matti Kurhila M. Why Dronning Maud Land? Dronning Maud Land in Antarctica Figure 1 has turned out to be a fruitful area to study anorogenic magmatism. Nunataks that break through the continental ice sheet are void of vegetation and show evidence of multiple anorogenic magmatic events in the past.

The emplacement of Karoo CFBs was followed by the dispersal of the Gondwana supercontinent and generation of smaller continents that we presently recognize as Africa, South-America, Australia, and Antarctica Figure 2. The oldest anorogenic igneous rocks of Dronning Maud Land are over million years old and are related to the dispersal of an ancient Rodinia supercontinent, which preceded the formation of Gondwana.

These rocks have largely eroded away, however, and only the crystallized magma chambers of ancient giant volcanoes, rapakivi-granites Figure 4 , remind us from anorogenic events of those times. But how is it possible to generate such vast amounts of magma in general? What kind of mantle materials were the initial sources for the melts, and at what depths and temperatures? Vestfjella hosts a versatile collection of distinctly evolved flood basalts and some of the most extraordinary Karoo-related rock types, ferropicrites, which have avoided lithospheric contamination and provide direct geochemical information from the ultimate sources of the CFBs Figure 8.

These xenoliths have led us to the secrets of the Precambrian basement, over billion years into the origins of the Rodinia supercontinent.

This video will go down in history purely by virtue of bringing together three of pop’s most important women — and putting them in absurdly perfect outfits in the process.

Watch “Don’t Call Me Angel” here. Marina Diamandis — known professionally as Marina and previously by the stage name Marina and the Diamonds — radiates summertime happiness joy in the video for “Orange Trees. Watch “Orange Trees” here. At its most basic level, “A Lot” celebrates the complexities of family, especially in black communities. It’s an ode to the joyful moments and the deep abiding love, but also the struggles and baggage.

Watch “A Lot” here. Although the colorful visuals for Khalid’s “Talk” don’t totally align with the song’s anxious theme, it can easily be read as an homage to Drake’s “Hotline Bling,” which is one of the best comparisons for a modern music video. Watch “Talk” here. Although “Wake Up” doesn’t quite recreate the bizarre magic of last year’s “Sicko Mode,” the visuals are still striking enough — disconcerting, yet graceful — to make a lasting impression.

Watch “Wake Up” here. The “Cool” video, while nothing particularly new or special, is pure bubbly joy.
