In 1900, he married Mary Georgina Newton, and they had a daughter, Eileen Mary, the next year.ĭuring his nine years in Montreal, Rutherford collaborated with the young Frederick Soddy (winner of the Nobel Prize in Chemistry in 1921) on ground-breaking research into the transmutation of elements. In 1898, Rutherford was appointed to the vacant chair of physics at McGill University in Montreal, Canada. In 1897, he was awarded a BA Research Degree and the Coutts-Trotter Studentship of Trinity College, Cambridge. During Rutherford’s investigation of radioactivity at Cambridge, he invented an ingenious detector for electromagnetic waves, and coined the terms “ alpha” and “ beta” to describe the two distinct types of radiation emitted by thorium and uranium. Thompson (soon to become the discoverer of the electron). He continued with research work at Canterbury College for a short time, receiving a BSc degree in 1894, before traveling to England in 1895 for postgraduate study at the Cavendish Laboratory at the University of Cambridge, where he studied under J. He graduated with an MA in 1893, with a double first in Mathematics and Physical Science. He was educated at Havelock School and then, at age 16, Nelson Collegiate School, before winning a scholarship to study at Canterbury College at the University of New Zealand in Wellington in 1889. He was awarded the Nobel Prize in Chemistry in 1908 “for his investigations into the disintegration of the elements, and the chemistry of radioactive substances”.Įrnest Rutherford was born on 30 August 1871 in Spring Grove (now called Brightwater) near Nelson, New Zealand, the fourth of twelve children of a Scottish farmer and an English schoolteacher. He is also credited with the discovery of the proton in 1919, and hypothesized the existence of the neutron. In 1911, he was the first to discover that atoms have a small charged nucleus surrounded by largely empty space, and are circled by tiny electrons, which became known as the Rutherford model (or planetary model) of the atom. He also had the great pleasure of seeing several of his close associates receive their own Nobel Prizes, including Rutherford in chemistry (1908) and Aston in chemistry (1922).Ernest Rutherford, 1st Baron Rutherford of Nelson was a New Zealand chemist who has become known as the “father of nuclear physics”. Thomson received various honors, including the Nobel Prize in Physics in 1906 and a knighthood in 1908. In 1913 Thomson published an influential monograph urging chemists to use the mass spectrograph in their analyses. His nonmathematical atomic theory-unlike early quantum theory-could also be used to account for chemical bonding and molecular structure (see Gilbert Newton Lewis and Irving Langmuir). Of all the physicists associated with determining the structure of the atom, Thomson remained most closely aligned to the chemical community. He was a good lecturer, encouraged his students, and devoted considerable attention to the wider problems of science teaching at university and secondary levels. Even though he was clumsy with his hands, he had a genius for designing apparatus and diagnosing its problems. In 1884 he was named to the prestigious Cavendish Professorship of Experimental Physics at Cambridge, although he had personally done very little experimental work. He was then recommended to Trinity College, Cambridge, where he became a mathematical physicist. Instead young Thomson attended Owens College, Manchester, which had an excellent science faculty. His father intended him to be an engineer, which in those days required an apprenticeship, but his family could not raise the necessary fee. Ironically, Thomson-great scientist and physics mentor-became a physicist by default. His assistant, Francis Aston, developed Thomson’s instrument further and with the improved version was able to discover isotopes-atoms of the same element with different atomic weights-in a large number of nonradioactive elements. Here his techniques led to the development of the mass spectrograph. Thomson’s last important experimental program focused on determining the nature of positively charged particles. His efforts to estimate the number of electrons in an atom from measurements of the scattering of light, X, beta, and gamma rays initiated the research trajectory along which his student Ernest Rutherford moved. In 1904 Thomson suggested a model of the atom as a sphere of positive matter in which electrons are positioned by electrostatic forces. Structure of the Atom and Mass Spectrography

Okay, that seems pretty straightforward, right? What is the tricky part?
The second approach relies on recognizing a triangle. We can substitute these values into the equation and then solve for, the hypotenuse of the triangle and the diagonal of the square: Remember the formula:, where and are the lengths of the legs of the triangle, and is the length of the triangle's hypotenuse. Once you recognize the right triangle in this question, you can begin to use the Pythagorean Theorem. Furthermore, the diagonal bisects two ninety-degree angles, thereby making the resulting triangles a triangle.įrom here you can go one of two ways: using the Pythagorean Theorem to find the diagonal, or recognizing the triangle as a triangle. By drawing the square out and adding the diagonal, you can see that you form two right triangles. The first step is to realize that this is really a triangle question, even though it starts with a square. We can see that the three angles in an isosceles triangle add up to 180°.The answer can be found two different ways. We divide 150° into two equal parts to see what angle ‘a’ and ‘b’ are equal to. The size of these two angles are the same. We can subtract 30° from 180° to see what angle ‘a’ and ‘b’ add up to.Īnd so, angles ‘a’ and ‘b’ both add up to 150°.īecause angles ‘a’ and ‘b’ are both opposite the marked sides, they are equal to each other. This time, we know the angle that is not opposite a marked side. Here is another example of finding the missing angles in isosceles triangles when one angle is known. We first add the two 50° angles together.Īngle ‘b’ is 80° because all angles in a triangle add up to 180°. To find angle ‘b’, we subtract both 50° angles from 180°. Now to find angle ‘b’, we use the fact that all three angles add up to 180°. This means that it is the same size as the angle that is opposite the other marked side. This angle is opposite one of the marked sides. Here is an example of finding two missing angles in an isosceles triangle from just one known angle. If the known angle is not opposite a marked side, then subtract this angle from 180° and divide the result by two to get the size of both missing angles.Add these two angles together and subtract the answer from 180° to find the remaining third angle. If the known angle is opposite a marked side, then the angle opposite the other marked side is the same.If only one angle is known in an isosceles triangle, then we can find the other two missing angles using the following steps: How to Find Missing Angles in an Isosceles Triangle from only One Angle We can also think, “What angle do we need to add to 70° and 70° to make 180°?” The missing angle on the top of this isosceles triangle is 40°. We subtract the 140° from 180° to see what the size of the remaining angle is. The missing angle is not opposite the two marked sides and so, we add the two base angles together and then subtract this result from 180 to get our answer.Īngles in an isosceles triangle add to 180°. The two base angles are opposite the marked lines and so, they are equal to each other. This is because all three angles in an isosceles triangle must add to 180°įor example, in the isosceles triangle below, we need to find the missing angle at the top of the triangle.

Here, you can always revisit an older version to review details you want to re-emphasize in rewrites. Draft 2.0.1: Rewritten rough draft with a minor tweak (or “patch”) to the protagonist’s motivation.Draft 2.0: Rough draft fully rewritten with feedback from critique partners.Draft 1.5: Rough draft with some rewrites. Smaller changes are like patches (the version’s third number) and rewrites might be closer to updates (the second number) rather than a new version release/new draft (the first number). It takes cues from software versioning, noting that not every change means a new draft. While this started as more of a joke between writers on social media, it’s a great middle-of-the-road way to think about drafting. Plus, for larger projects like novels, you need to divide your manuscript into parts and have a file system in place to keep track of your revisions. But you may risk losing details from earlier drafts because of the repeat saves. The advantage here lies in simplicity: you have fewer files to juggle since you’re saving to the same file over and over. Which means when saving a manuscript to a file, you wouldn’t alter the file name until you completely rewrite that chapter, section, or piece. By this definition, only full rewrites of a piece count as a true draft. Keep reading for more on how this draft spectrum works. Middle-of-the-road: The fiction patching method.It’s impossible to say: “oh, writing a novel will take five drafts.”īecause the definition of “draft” can vary so much, it’s useful to think about drafting on a spectrum: Which means every writer’s version of “the writing process” will look different. There are as many ways to define the word “draft” as there are writers. The biggest problem with breaking down the writing process from first to last draft can be linked back to one little detail: A rose by any other name: What’s in a draft? Unfortunately, you’re more likely to answer “how many licks does it take to get to the center of a Tootsie pop?” before knowing how many drafts you’ll need before publication. It’s natural to wonder: how many drafts will it take before my story is ready to publish? For write-to-publish newbies, you might want to know what you’re getting into, especially if you’re working on a large project like a novel. So you’ve decided to write a story and hope to publish it.

Right now I’m not interested in tracking those, but I might in the future. For example, some gardeners like to track their expenses to help budget for the next growing season. Personally, I used a 3-ring binder because it allows me flexibility to insert and remove sheets. And there is a variety of journals to choose from, whether it be a spiral notebook, 3-ring binder, or a commercially-published garden journal. What You Need to Start a Vegetable Garden Journal?Įvery journal is personal, including a vegetable garden journal. It’s tailored to your skill level and what YOU think is important to learning and improving your gardening skills. That’s what is so great about keeping your own gardening journal. It can be simple and basic, or comprehensive and detailed. Quite simply, it’s a record of your vegetable garden – what is planted where, how many of each plant, which plants thrived and which ones didn’t, and anything else worth recording that supports and improves your garden. The solution to keep my vegetable garden organized for years to come? Enter the vegetable garden journal.Īdmittedly, I should have started a vegetable garden journal back in the spring, but a gal has got to start somewhere, right? What is a Vegetable Garden Journal? And I learned that while Lacinato kale grows well in my garden, we absolutely despise the taste.īut will I remember that next spring? Probably not. Next year, I’ll struggle to recall – Which crops did I plant? Was there enough of it? Did it grow well? For example, arugula grew amazingly in my garden, so I need more than this year’s 6 seedlings. Next year I can’t wait to plant another larger vegetable garden.īut here’s the problem. Some crops are growing like crazy, others are just stunted sprouts. And instead of the short-list of peppers and tomatoes, I planted a wider variety of veggies – eggplants, radishes, onions, lettuces, leeks, gerkins, celery, carrots, garlic, watermelon.Īnd now it’s the end of July. So this spring, I bought and sowed seeds for the first time. I was nervous that the trend would continue through the summer and my family wouldn’t have fresh fruits and veggies available. Fresh Produce: In spring when covid-10 first hit, my grocery store struggled keeping fresh produce stocked on the shelves.Quality Time: The whole family was home more (as were so many of us) so gardening was a perfect way to simultaneously occupy them and work on the house.Nothing too spectacular – a couple of tomato, cucumber and peppers, bought as seedlings from a big box home improvement store.īut this year with Covid-19 I dug more seriously into gardening (pun intended).

Free to vary: Dessert analogy Example: Dessert analogyImagine your roommate has a sweet tooth, so she’s thrilled to discover that your college cafeteria offers seven dessert options. The following analogy and example show you what it means for a value to be free to vary and how it’s affected by restrictions. To put it another way, the values in the sample are not all free to vary. As a result, the pieces of information are not all independent. When you estimate a parameter, you need to introduce restrictions in how values are related to each other. There are always fewer degrees of freedom than the sample size. NoteAlthough degrees of freedom are closely related to sample size, they’re not the same thing. When the sample size is large, there are many independent pieces of information, and therefore many degrees of freedom.

The idea is that you will never throw this master list away, only add to it. One of the best ways to craft a resume is by starting with a master list of your skills, knowledge, experiences, etc. No two resumes are the same, but there are some guiding principles that you can follow. For this reason, your resume should professionally communicate the most important information about you so the reviewer can make an educated decision. It tells the recruiter or hiring manager objective information about you which can be used to decide if an interview is the appropriate next step. A resume often serves as an organization’s first impression of you. That and if they completely remade Mario 64 similar to Crash and Spyro it makes the other two games look older and not show an accurate evolution of the series so they'd have to remake them too. Think of this the Crash and Spyro releases did not sell as well as Mario 3D All-Stars and that is just a fact.
