Less Than 1,000 Days Until the Next Total Solar Eclipse in the United States

On Monday, August 21, 2017, a total solar eclipse will be visible in some areas of the United States. This is now less than 1,000 days away. The event has been a long time coming. While the last total solar eclipse to be seen in the United States occurred in 1991, that event was limited to Hawaii. Before that, the last solar eclipse visible from the continental United States was on February 26, 1979.

While the 1979 event tracked across Oregon, Washington and Montana, people in 12 states will see the 2017 event. Both eclipses started in Oregon. The earlier one then tracked up into Canada. The 2017 eclipse starts in Oregon, travels across the central United States before finishing far out to sea beyond South Carolina.

A total solar eclipse is a rather rare occurrence. Estimates place the likelihood of any point on Earth experiencing one only every 400 years. This is not absolute, however. Several Oregon locations saw the 1979 eclipse and they will see the 2017 event as well. For them, experiencing two solar eclipses in a little more than 35 years is quite unusual. Closer yet are the cities of Carbondale, Illinois, and Cape Girardeau, Missouri. Residents there will see the 2017 eclipse as well as another in April, 2024. This separation of less than seven years for these two eclipses is very unusual. Of course, it may be hundreds of years before these cities see another.

To be a total eclipse, the moon must completely obscure the sun, for an observer standing on Earth. This can occur monthly, at New Moon. Ordinarily, however, the moon passes either above, or below, the sun’s position, as viewed from Earth. As a result, the moon’s shadow normally sweeps across open space. On rare occasions, as the moon passes directly in front of the sun, a shadow is cast upon the surface of the Earth. If the sun is partially obscured, a partial eclipse results. If the sun is completely obscured, a total solar eclipse occurs. The moon is much smaller than the sun, of course. In fact, the moon is some 400 times smaller. In an astronomical twist, the moon is also 400 times closer to the Earth. This makes the apparent size of the moon very close to the apparent size of the sun. When the moon passes directly in front of the sun, it is able to completely eclipse the sun, for some viewers on Earth.

The shadow cast by the moon, however, is very small. Depending on the distance between the Earth and the moon, which varies somewhat, the moon’s shadow will darken a strip of Earth about 70 miles wide. This strip is called the Zone of Totality. Those people located within this zone will experience a total solar eclipse. Those near, but outside, will see a partial solar eclipse.

On August 21, 2017, the sun is eclipsed for as much as 2 minutes and 40 seconds at the maximum point. Hopkinsville, Kentucky happens to be located at this point. People not located there may see a shorter eclipse duration. Those located outside the zone of totality will only see a partial eclipse. Some cities that will experience totality include Nashville, Tennessee, Kansas City and St. Louis, Missouri. The 2017 eclipse will potentially be seen by millions of people located across the United States.

Each total solar eclipse is unique, but there are similarities. The Earth will darken over time as the moon obscures more and more of the sun. This is the partial eclipse phase. As totality approaches, the amount of sunlight striking the Earth will be greatly diminished. The sky will become similar to twilight. Colors normally seen at sunset will be visible during the day. Birds, animals and insects will be fooled into believing that night is falling. Some will return to their nests or roosts. Nocturnal creatures will begin to emerge. These effects often happen even if a total solar eclipse occurs early in the morning. After totality ends, another partial eclipse phase occurs until the moon passes beyond the sun’s location.

The biggest factor that cannot be predicted with certainty is the weather on August 21, 2017. Cloudy weather could obscure the eclipse for interested observers. As a result, many people examine historical weather patterns in order to determine prime eclipse viewing locations. Since the 2017 event occurs in August, there are some rather promising weather possibilities. In Oregon, the August weather tends to be sunny and dry, perfect eclipse conditions. Morning fog, storms, or clouds, could thwart eclipse viewers, however.

Idaho and Wyoming residents will also experience the 2017 eclipse. The weather in these states could allow a very good eclipse viewing experience. The eclipse occurs fairly early in the day, lessening the possibility of localized thunderstorms.

As the total solar eclipse tracks across more states, from Nebraska to South Carolina, the possibility of inclement weather increases. These locations will experience the eclipse later in the day. Afternoon storms, or hazy weather, could be encountered. Such weather could limit the eclipse experience.

Many US cities have already begun planning for the August 21, 2017 total solar eclipse. The event represents an opportunity to entertain tens of thousands of visitors to cities located within the zone of totality. With proper attention to details, cities can provide a favorable eclipse experience that also highlights the attractions of the local area. Weather permitting, of course.

Bonus Facts:

– the distance from the Earth to the moon increases each year. In less than 1.5 billion years, the moon will not be close enough to produce total solar eclipses. After that, only partial or annular eclipses will occur.

– when the moon eclipses the sun, the sky darkens enough to allow planets and bright stars to be seen in the daytime. On August 21, 2017, the bright star Rigel should be visible low in the south. – Albert Einstein predicted that a total solar eclipse could provide direct proof of the General Theory of Relativity. He postulated that the eclipsed sun would cause light to be bent, for an observer on Earth. This would be proved as stars located behind the sun would appear to be shifted in location. This visual evidence was demonstrated during an eclipse in 1919.

– as the moon passes in front of the sun, it blocks enough sunlight that the solar corona, the super heated atmosphere, becomes visible to people on Earth. The shape of the corona is different during each eclipse as it is influenced by the level of magnetic solar storms, which constantly changes.

– ancient civilizations did not understand the science responsible for total solar eclipses. Eclipses were attributed to supernatural causes and thought to be bad omens.

– the theoretical maximum duration of a total solar eclipse is about 7 minutes. The 2017 eclipse is less than half this duration, at 2 minutes, 40 seconds for those located in Hopkinsville, Kentucky.

– the sun is not safe to view during any portion of the partial eclipse phase. Even if only 1% of the sun is visible, observers risk damage to their eyes through direct observation. At this eclipse stage, the sun appears to be dim enough to view. Unfortunately, the lit portion still transmits full force sunlight to the optic nerve. Because the level of light is so much lower than normal, the observer feels no urge to avert their gaze. Moreover, the optic nerve does not contain pain receptors so victims are unaware that their eyesight is being damaged. Proper eye protection is vital for all observers of the partial solar eclipse phase.

LYFT Driverless Car Network

Not so long ago in the past and to be more specific, it has been just 4 years since the announcement of LYFT as a large competitor for Uber. Today the company has grown in size and popularity and is definitely making waves in terms of pricing along with coverage. This company was first thought of as a fly by night company to be hauled away in the next big growth of Uber. However, this has been a far thought for LYFT. This company has been silently building itself and engulfing its efforts in technology. Their most recently talked about innovation to be brought online will be a Driverless Car Network.

Now many have bogged at the idea of Driverless cars, but they are becoming more and more trendy as time moves on. Innovators such as Mercedes has put self-driving capabilities in many of its models, followed by General Motors Nissan, Toyota, Audi, Volvo, and Tesla. Self-driving cars are no longer a talk of possibility; they are now here to stay. For that reason, GM has jumped on the forefront to invest $500 million in LYFT’s initiative for their Driverless Car Network. This effort essentially will change the way how we commute and reduce the risks associated with impaired drivers or drivers which are inebriated. As opposed to going out in the car yourself to make a pickup of a friend or parents, a simple call or selection in the LYFT app will send a Driverless LYFT vehicle to the pickup aid of the designated person and taking them safely to their next location without incident. This means that the 94% of road accidents which are caused by human error will be drastically dropped due to the car being driven by Artificial Intelligence. Roadways will be more accessible with less vehicles cluttering the highways as more accessibility for carpools and more ability to work while riding effortlessly to work or to school. Many traffic jams are accounted by accidents which occur during morning or evening rush hour. Imagine not having to deal with such delays and being able to effortlessly get home while finishing up a project for work, school, or leisure. This is the future the LYFT is in the process of unveiling to the world in 2017. As far as designs for the Driverless Car Network that LYFT will unveil in 2017, its all just speculations as LYFT along with General Motors has managed to keep talks or leaks about the designs under heavy guard. At the moment these companies stand at the cusp of changing the way how we all use our vehicles and LYFT is the company that is driving the helm.

Top 5 Features Added in Revit

A building information modeling (BIM) software, Autodesk Revit, has been useful for architects, structural engineers, MEP engineers, designers and contractors, enabling them to design structures and buildings in 2D and 3D, as well as being 4D BIM capable. It’s first version was released more than a decade back and since then it has seen many updates and new version releases, some have been just incremental updates serving for bug corrections and some have been significant technological updates.

Compared to the 2017 update, the previous 2 editions did not provide any significant upgrade until their ‘release 2’ (R2) editions were released. The 2017 update brings about 50 new, refreshing features which will prove to be immensely useful in creating BIM models. All the new features within the update are equally important and will be useful during the life cycle of a project, but out of those let us discuss the 5 most important features from Revit 2017. 1. Text Editing:

The most awaited feature in Revit since the time it was introduced, text editor has been included in the latest edition of Autodesk Revit. This provides a completely redesigned text engine which is compatible with imported files such as AutoCAD DWG files. The text editor in Revit 2017 also brings corrections to the flaws of text editor from earlier editions and lets users seamlessly switch between text editing mode and viewing mode without causing any unexpected disruptions in text.

2. Global Parameters:

Global parameters feature which was introduced in Revit 2016 R2 version, has received a much needed update in the 2017 edition. The latest update brings in the power of parametric families into the project environment. Applying global parameters to multi-segments is possible in this version, also grouping the parameters becomes easier, as does filtering and reordering. Even though the upgrades do seem to bring a lot of additional features, they do come with their limitations, such as the parameters can only be assigned to certain system family categories and only to user defined instance properties.

3. View Template:

View template is a very simple yet powerful feature added in Revit 2017 which enables the user to share data and reuse schedules. This feature automatically updates all the schedule changes whenever they are affected within their respective templates.

4. Calculated Values in Annotations:

An essential and a long overdue feature introduced in Revit 2017 is Calculated Values in Annotations. It is a useful feature that allows the user to document projects with annotations that allow calculated values and which obey pin restrictions maintaining consistency and accuracy of the project. A tag created with calculations in it can be used with any tag type and pinned to an element allowing the user to reposition that element without actually moving the pin position.

5. Railing Host:

Railing Host or Hosted Railings, is another valuable feature introduced in Revit 2017 (SHOULD THIS SAY 2017?) along with Calculated Value in Annotations feature. With this feature it is now possible to host the railings on Walls, Roofs or Slab Edges and the railings will adjust with variations in slopes and surfaces.

There are a host of other additions and updates in Revit 2017 apart from the ones listed above. It remains to be seen what if any flaws exist during real time use or if they truly result in the enhancements promised. Although, considering the supposed flaws that may exist, Revit 2017 is a huge step forward.

The Features Of Soccer Cleats

Soccer cleats refer to a firm ground soccer shoe, fitted with studs or cleats to provide traction on most grass surfaces and outdoor soccer fields.

The first soccer shoes were ordered by King Henry VIII in 1526 when he wanted another pair to play football with. One that was tougher than his ordinary shoes. As the game got formalized in the mid 19th century, so did the accessories one needed to have while playing the game, the most important of which were the football shoes.

Vulcanization of rubber was an important invention for the manufacture of cleats whose primary purpose was protection of the players’ feet. And so on from there, many innovations and generations later, football boots have come to represent the advancement of shoe making technology and materials and its importance in football, a game which enjoys absolute popularity amongst all the nations of the world. Today’s soccer cleat

Is not built so much for protection as for performance enhancement of the player! It does not even cover the ankle of the player. The cuts and organization of the studs are to suit different purposes. Amateur players use plastic studded cleats for hard ground. A wet ground requires detachable studs for better grip. These could be metal, plastic or rubber. Rubber soles are provided for indoor football shoes and there are special shoes for artificial turf.

Football blades where the studs have blades facing in different directions to minimize ankle injury to the wearer and deliver excellent grip are also an innovation that has drawn flak for causing a disproportionate number of injuries to other players.

A combination of synthetic fibers with or without leather is used for the upper, nowadays, with emphasis on the lightness of the boot. Carbon fiber as a new material, provides extreme lightness and is extremely flexible.

Additional features have been introduced like rubber ridges and shaping the boot for the ball enhance the player’s performance. There are shoes fitted with microchips that capture’s the player’s performance metrics and transmits it to a tablet or PC.

The latest is the environmentally friendly shoe, made with recycled and renewable material. This is also extremely lightweight.

Football cleats of the Future – Some interesting crystal ball gazing

· One young player predicts that the cleats of the future will have retractable studs, allowing him to use them as ordinary shoes· Autolacing capabilities which will be good – the wearer, after tying the laces steps back into the heel of the shoe. While stepping back, he pushes a lever which lock the laces in place. Then the lever is disconnected in case the player steps back again while playing.

· Recyclable material and carbon fibers used in building aircraft will definitely be the order of the day in creating lightweight boots that contain material used in the last world cup! Not only that, each pair of boots will be recycled and rebuilt to suit that customer’s requirements.

Boots that fit like a sock… such silhouettes will be more in demand for better performance and comfort.

A Colour Forecast For Spring 2017

Forget the monochrome look, forget restraint. One of the strong trends that we can look forward to in spring 2017 is vibrant colour. Think wacky, age of Aquarius style psychedelia. Many of the looks that will come to the fore in spring of next year are going to be a riot of colour. This is great for those of us who love vibrant shades and are not afraid to stand out from the crowd, though perhaps not so good for shrinking violets or those with a more muted aesthetic.

Tie dye is back and there is something of a resurgence of the hippie fashion aesthetic. For Resort, designers showed a range of tie-dye clothing. Both inner and outerwear items were shown and there was plenty of colour on display, much of it in bold, rich tones that are all about the character and the playful wackiness. Spring summer 2017 could be the time to revisit the Summer of Love. But this psychedelia has a sort of contemporary edge, with bold shapes, geometric designs and a strong line in global multiculturalism that reflects our more connected modern age. The way to wear this multi-coloured extravaganza is definitely to give it some gusto, but also a bit of an edge. Think whimsy but with a slightly harder urban slant.

The key to looking up to date and not like you have been lost and wandering on the hippie trail since the 60s is to choose pieces with a more modern shape when going for rainbow coloured clothes. Mismatched patterns and quirky combos will edge this look into another spring summer 2017 look – the chic geek. The idea is that pretty much anything goes and you should let your freak flag fly, showing your own unusual and unique personality through the way you dress.

This colour extravaganza borrows not only from the pschedelia of the 1960s but also from the colourful aesthetic of Tibet, its woven fabrics, strong patterns and bright colours, all with a slightly spiritual bent. There is also a large dose of inspiration taken from Cuba, a nation opening to the US for the first time in over fifty years and one with a strong culture and tropical aesthetic. Colour inspiration is also taken from the northern Californian coast, rich mid-tone blues and beachy hues mingle in with brighter tropical colours. No matter where you look, the spring summer 2017 trends are all about colour. Developing a really good colour sense and knowing which colours will suit you is the key to looking good and finding your own perfect look for the coming seasons.
