The idea that the objective, or light-gathering element, could be a mirror instead of a lens was being investigated soon after the invention of the refracting telescope. Galileo heard about it and, in 1609, built his own version, and made his telescopic observations of celestial objects. The actual inventor is unknown but word of it spread through Europe. The earliest existing record of a telescope was a 1608 patent submitted to the government in the Netherlands by Middelburg spectacle maker Hans Lipperhey for a refracting telescope. Main article: History of the telescope 17th-century telescope The root of the word is from the Ancient Greek τῆλε, romanized tele 'far' and σκοπεῖν, skopein 'to look or see' τηλεσκόπος, teleskopos 'far-seeing'. In the Starry Messenger, Galileo had used the Latin term perspicillum. The word telescope was coined in 1611 by the Greek mathematician Giovanni Demisiani for one of Galileo Galilei's instruments presented at a banquet at the Accademia dei Lincei. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. They were used for both terrestrial applications and astronomy. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. Nowadays, the word "telescope" is defined as wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. Originally it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. The 100-inch (2.54 m) Hooker reflecting telescope at Mount Wilson Observatory near Los Angeles, USA, used by Edwin Hubble to measure galaxy redshifts and discover the general expansion of the universe.Ī telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. For other uses, see Telescope (disambiguation).

But you got to do what you have to do, but I recommend, take the vaccines. “I believe totally in your freedoms, I do. Look at exactly what he said on vaccines – both before and after he was booed: What’s worse is that Trump has zero inclination to try to control the creature he has built. And to do so in a state that is fourth in the country in overall cases of Covid-19 per 100,000 people, and fifth in deaths per 100,000 people, according to The New York Times. It’s that mentality that leads people to boo vaccines that are more than 90% effective in preventing serious illness and death from a pandemic that has already killed more than 628,000 Americans.

Mehta also specified that any argument about testimonial immunity would only apply to the second count for which Navarro was charged - related to his refusal to testify - and the first count, related to the production of relevant records, would be subject only to executive privilege.THE POINT - NOW ON YOUTUBE! In each episode of his weekly YouTube show, Chris Cillizza will delve a little deeper into the surreal world of politics. Notably, in a separate hearing in the courtroom adjacent to the one where Navarro was testifying, federal prosecutors in Trump's prosecution revealed the former president's legal team had mounted multiple sealed court battles over assertions of executive privilege in an unsuccessful attempt to stop a number of grand jury witnesses from testifying in the special counsel's probe.īefore Monday's hearing, Mehta ruled that Navarro would need to show formal, concrete proof during Monday's hearing that such protections had been invoked to make the privilege or immunity defense at trial. 6 House select committee and not to Navarro. The defense contended that it would have been "inconceivable" that Trump would grant executive privilege to all his other senior advisers who had been subpoenaed by the Jan. 6 subpoena, much less evidence that supports the claim that he formally shielded Navarro from testimony. When asked about his communication with Trump, Navarro said he did not email him directly and communicated with him through his aides, adding, "He's not a text guy."īut the Justice Department said there was nothing to prove that Trump even saw the Jan. Stanley Woodward, Navarro's defense attorney, said that he, too, wished there were more physical documentation of the executive privilege, but he argued that the "unconventional approach" did not invalidate Navarro's right to defend himself by saying he thought he had been formally restricted from speaking to Congress. "I still don't have any inkling of what the president's words were," he said. Judge Mehta raised questions about the existence of any documented evidence substantiating Navarro's claim that Trump directed the invocation of the privileges. Prosecutors had urged the court not to hold Monday's evidentiary hearing at all, arguing Navarro had not provided the court with any actual evidence that Trump had actually invoked executive privilege or testimonial immunity - certain protections afforded to presidents in specific scenarios - over Navarro's response to the congressional subpoena.īut in a ruling last month, Mehta wrote, "The court…will permit Defendant, through his own testimony or other evidence, to establish the factual predicate for the actual, proper invocation of executive privilege or testimonial immunity, or both, by the former President." 5, and the parties are estimating the proceedings will take just days to complete. After refusing to comply with the requests, Navarro was indicted on two counts of criminal contempt of Congress and pleaded not guilty. The select committee first subpoenaed Navarro for records and testimony in February 2022 as part of its investigation into efforts to reverse the outcome of the 2020 presidential election. Ostrich ferns produce two types of fronds. They have an upright growth habit and by late summer will often stand 4 to 6-feet tall, with a 3 to 6-foot spread. These native, clump-forming ferns have a big presence in the landscape. The plants grow relatively slow, but can eventually spread to cover a 2 to 3-foot area. Ghost ferns will not tolerate drought, so it's important to choose a planting location where the soil is consistently moist all season long. Plant in part to full shade and provide shelter from wind. The plants have an upright habit and silvery grey fronds with burgundy accents. This lovely fern is a hybrid between the lady fern and Japanese painted fern. Mature height is 1 to 2 feet tall with a similar spread. Plant in moist, well-drained soil that is relatively acidic. The plants are relatively slow-growing, but are also very long-lived. The dark green fronds have the same long, narrow shape as a Boston fern. and is particularly popular in the southeast, where the foliage stays green throughout the winter. Here are five types to consider:Ĭhristmas Fern. If hot weather causes your ferns to wither, cut them back to the ground and wait for them to regrow once temperatures cool down. For sites with dry soil, choose Christmas ferns or lady ferns. Interrupted ferns and cinnamon ferns are good for relatively sunny locations. There are some ferns that tolerate sun, provided the soil is rich and has plenty of moisture. Check the pH of the soil in the planting area and match the plant to the growing conditions. Most ferns are not fussy about soil pH, but some types prefer acidic soil. Before planting, take the time to work in some compost and peat moss. Most ferns grow best in loose, loamy soil that is rich in organic matter. In soggy areas or rain garden, consider including ferns along with other moisture-loving perennials such as monarda, Joe Pye weed and ornamental grasses. Most types will thrive when used as edging plants beside a stream or pond. Once established, they are an excellent ground cover and require much less attention than turf grass.Īs a general rule, ferns prefer moist soil. Consider replacing the most difficult areas with ferns. If your yard is shady, it can be challenging to maintain a good-looking lawn. Use them as specimen plants or for background plantings, or interplant them with other shade loving plants such as hostas, astilbes, dicentras and caladiums. Using Ferns in Your Yard and Gardenįerns make an excellent addition to any shady garden. In a garden, they can introduce a sense of calm, harmony and permanence. Plus, they are incredibly easy to grow and are rarely troubled by diseases or pests, including deer and rabbits.įerns have an air of untamed wildness about them. That's unfortunate, because these graceful, long-lived perennials have so much to offer! They come in a wide range of colors, shapes, and sizes. Ferns are plentiful in the wild, yet it's relatively unusual to see them growing in a home landscape. It also now includes more detailed progress indication while a task is running, including a time remaining estimate, and file processing and transfer rates are now charted in real time during backup tasks. Interface-wise, CCC's main window has been redesigned for Dark Mode, and now has a smaller desktop footprint while making many of the controls and font sizes larger. There's also a new Snapshot Navigator, which allows users to step through older versions of their backups and get a preview of files as they were at specific points in time. So rather than scheduling hourly or daily tasks, CCC can run tasks when a specific amount of data has changed on the disk, with the added ability to limit the number of automated tasks that run in a given time window.Įlsewhere, a new Preview feature offers an advance look at what changes will be made to the destination before a backup runs, while new Backup Audits record detailed information about the transactions that occurred during the task, such as files copied, files updated, folders created or updated, and files deleted or archived.ĬCC's new Compare feature offers a visual comparison of a task's source and destination, and provides details if the differences are the result of a task filter. Using the same underlying technology that's used by the "Quick Update" feature, CCC 6 also offers a new automation option that allows users to have a task run when a threshold of data changes have occurred at the source. To achieve this, CCC 6 now uses the macOS FSEvents service to check for a list of folders modified on the source since the last backup, rather than scanning every folder for changes. Bombich Software has released version 6 of Carbon Copy Cloner, the first major update to the backup program and Time Machine alternative in over four years.Īpart from offering the ability to make bootable backups on Intel and Apple Silicon Macs, the new-look CCC 6 includes a number of additional features, including a "Quick Update" to existing backups that is said to be up to 20 times faster. The first time I tried this technique I didn't have a lot of success, but after repeating the process a few times I was able to draw a circle without a problem. A horizon line is defined and then one point is placed on the horizon line. Use linear perspective to create the illusion of space in your drawings. Remember too that if it doesn't look good the first time, try it again and again until it does look good. Learn how to draw with one point perspective. How accurately you are able to match what you see in the drawing on the left to the drawing on the right will determine the success of your drawing. I'll say thing again because it's very important. Once you have a clear idea of where your circle should cross which lines, go to your perspective grid, and before you draw anything, put a small point on each of the lines that the circle crosses over exactly at the point where the circle meets the line. Take note of the exact points where the lines of the circle cross the lines of that perspective grid. Look closely at the top left area of the circle on the left. Your ability to match what you see in the two images will determine how well your circle looks. Pay careful attention to look at where the circle is passing through the guide lines in your perspective grid on the left. You can also see the circle drawn in perspective. You can see the construction grid that you created and it now has a circle drawn on top of it. Look at the square in the bottom left of the step 7 image. We have seen students enjoy a holistic and hands-on method.Īlso, Pencil and Chai conducts weekend sessions.Here's where all of your hard work in constructing a 1 point perspective grid is going to pay off. Yet, Sampratishta is the first art school to provide Diploma courses in Bangalore. Of course, Art schools structure their foundation programs in different ways. There are many Art Schools around Bangalore that provide the necessary technicalities. One-point perspective illustration of boxes above and below a horizon line with vanishing point and convergence lines. WHAT ARE THE FINEST ART INSTITUTES IN BANGALORE? What if there are two vanishing points? In fact, where do you see two vanishing points? Read our next blog about 2 points perspective. In fact, these lines create an illusion of distance and make drawings more realistic. The foreshortened lines orient 90 degrees to the picture plane. Next, draw the parallel lines perpendicular to it. Draw the horizontal lines parallel to the horizon line. The horizontal and vertical lines are in parallel with the picture plane. Also, the viewer can see the vanishing point located on the horizon line. In fact, the surfaces facing the viewer appear as their true shape, i.e. One-point perspective is appropriate when you can have a frontal view of the subject. WHEN CAN YOU APPLY ONE-POINT PERSPECTIVE? This method is quite popular among comic creators, cartoonists, architects and interior designers. Moreover, it represents the viewer’s level of sight. Also, lines and shapes in a drawing are present in reference to a single line, called the horizon line. This method creates three-dimensional and realistic drawings. One-point perspective is a drawing method where you use a flat drawing surface. The vanishing point can be on, above or below the horizon line. Yet, there is only a single one-point vanishing point. Also, they meet at the same vanishing point. Parallel lines of infinite length appear as converging lines. Thus, all the objects disappear at the vanishing point. Objects get smaller as they recede towards infinity. Because the table is sitting in the horizontal plane, its sides will flow into the vanishing point, whereas the horizontal lines will stay horizontal. In this case, let us start simply with a table. The same concept applies when drawing objects in the room. I wish you many pertinent pencil strokes! WHAT IS A VANISHING POINT? Step 2: Lightly Sketching Objects In the Room. Let me talk about one-point perspective today. Perspective drawings can be from one-point all the way up to 6-points. It is about two parallel lines meeting at a vanishing point. One-point perspective revolves around the same concept. The road seems to meet at a single point from a particular distance. A downhill stretch of road is defined by a new set of parallel lines, which will meet. You might notice how things begin to get smaller as you move further away. An uphill stretch of road has its vanishing point above the horizon line. Imagine driving on a highway with beautiful surroundings. Thanks for your time! A happy customer, F.M. I would also like to ask you if there are any books that you would recommend for me, a high school junior planning on studying music in College.

I recently bought one of your books, Jazz Solo Series for Trombone, and after only two weeks i was beginning to see improvement in my improvisational skills. Please refer to the end of the book for a selected discography of Mark's favorite Jazz albums featuring great soloists. Section four, tracks 67, 68 and 69 are repeated choruses of the chord progressions to the above mentioned songs for extended practice. The first version being a prime example of how to approach medium swing Jazz and the second version covering the more complex and demanding style of Bebop Jazz with its faster tempos and more difficult melodic and harmonic note choices. Section three, tracks 61 through 66 are complete worked out solos over the chord changes to the popular Jazz standards “Stella By Starlight”, “Take the A Train” and “There Will Never Be Another You.” There are two solos for each of these three examples, an easy version followed by a more difficult one. Section two, tracks 37 through 60 cover all twelve keys using 1-V1-11-V-111-b111-11-V-1 chord progressions. This book is divided into four sections: Section one, tracks 1 through 36 cover all twelve keys using 11-V-1 and 11-V-111-V1-11-V-1 chord progressions. There are 66 examples in the book, starting at a somewhat easy level and gradually increasing in difficulty throughout the book. 'Kackle Jackle' features six Scott Wilson originals and three carefully chosen covers (from John Coltrane, Hank Mobley, and Joe Henderson) and has broad appeal across multiple formats.The Jazz Solo Series for Trombone by Mark Vega is a great instructional tool for musicians and music students to learn or improve their improvisational abilities in the jazz - swing idiom. He is joined in Stark Raving by a group of players that are not only Grammy-nominees and Downbeat Award-winners, but are renowned educators who have inspired thousands of young musicians. i thought about you showcase plays the blues jazz homepage links. Wilson has diverse international performance credits having shared the stage with jazz luminaries including Benny Green, Wayne Bergeron, Gordon Goodwin, Conrad Herwig, Wycliffe Gordon, Stevie Wonder, Jeff Coffin, Shelly Berg, Denis DeBlasio, Peter Erskine, Eric Marienthal, Bobby Shew, Slide Hampton, Terrell Stafford, Ron Blake, John Pizzarelli, Ed Shaughnessy, Alex Acuna, and others. In addition to his dynamic live and recorded performances on trumpet, he is regarded as one of the world's foremost proponents of the electronic valve instrument (EVI). Since earning two masters degrees from the University of North Texas and paying his dues on concert stages from Orlando to Osaka, Scott is in constant demand as a player, composer and educator. Scott Wilson has established himself as one of the rising stars of jazz - both as a performer and as a pedagogue. Kackle Jackle was a creation by trumpeter and EVI player Scott Wilson. Kevin Hicks is the transcriber of the solos and author of the book. The trombone teacher told Mingus to learn the notes of the clef but did not specify which clef.

But zero can't really be divided by two since the result is zero - neither a positive or negative integer.Ī: Zero times. Zero, on the other hand, is even since it is 2 times some integer: it's 2 times 0."Ī 2001 question takes us a little deeper: Is Zero Even?Īt numerous sites across the Internet the answer to the question whether zero is odd or even seems to be totally subjective, and the proofs used to justify 'even' (zero can be divided by two, therefore it is even), sound reasonable. The terms even and odd only apply to integers 2.5 is neither even nor odd. "Integers are the whole numbers, negative whole numbers, and zero. We’ll be looking at this extension below. Later when the number system is expanded to include the set of integers, they will be able to carry the concept over without much difficulty. Then have them divide several numbers by 2 (including 0) and let them see a second way to conclude that a number is even ( the remainder of the evens is 0 and the remainder of the odds is 1). So all the numbers in the list of multiples are the even numbers: 0, 2, 4, 6, …. We can (equivalently) say either that an even number is one that is exactly divisible by 2, or one that is a multiple of 2. Ultimately, we just have to go to the definition. You may want to review the multiplication facts for 2:Īfter writing these number facts out or reviewing them with the class you can ask them about patterns and eventually tell them that this is how they can create a list of even numbers. That means that when you divide by two the remainder is zero. An even number is a number that is exactly divisible by 2. If we didn’t call zero even, it would look like this:īut since zero was special in terms of sign, maybe it’s special here, too?ĭoctor Mateo answered, focusing on the definition: Hello Wendy, (Not sure about those negative numbers? We’ll get there!) Not bad! And every other number on the number line is even, so we can’t skip over the place where zero is. 30 is even, and it ends in zero), then for consistency, 0 itself must be even. 36 is even because 6 is even), and all numbers that end with the digit 0 are even (e.g. Wendy knows that zero is even, but can’t convince her students! Her first argument appears to be that since we can decide whether a number is even by whether its units digit is even (e.g. (We discussed 1 not being prime or composite in Prime Numbers: What About 0 and 1?) Is it just special the way that 1 is neither prime nor composite? It holds an even place in the number line. Zero after any other number is even because it can be divided by 2. Is zero odd or even? My 4th grade students are not satisfied with any explanation I can offer. Now let’s turn to the question of “parity” (oddness or evenness), with a question from 1998: Is Zero Odd or Even? Technically, if we’re talking about real numbers and not just integers, these should be: We previously discussed this in Talking About Negative Numbers. It is easy to say “positive” when you really mean “non-negative”, because you forgot to think about whether to include zero! Here are the non-negative numbers: Similarly, the " non-positive" numbers are the negative numbers together with zero. So the only difference between the set of positive numbers and the set of non-negative numbers is that zero isn't in the first set, but it is in the second. People sometimes talk about the " non-negative" numbers, and what that means is all the numbers that aren't negative, in other words all the positive numbers and zero. Here, positive numbers are green, negative numbers are red, and zero is neither: Zero is the dividing point, and is not on either side of the line. Since zero isn't bigger or smaller than itself (just like you're not older than yourself, or taller than yourself), zero is neither positive nor negative. Negative numbers are numbers that are smaller than zero, and positive numbers are numbers that are bigger than zero. The whole idea of positive and negative is defined in terms of zero. My name is David and I am in fifth grade at Kyrene De La Sierra in Phoenix.Īctually, zero is neither a negative or a positive number. My class and I are wondering if 0 is a negative or a positive number and why. We’ll start with a question from 1995: Why Zero is neither Positive nor Negative Last week we looked at some basics about zero now let’s look at whether zero is positive or negative, and then at the topic of the recent comment that triggered this series: whether zero is even or odd.
