Me: I need to finish the writing project I've been working on for years.

Also me: -does literally any other writing project-

[smallishdruid]

I DID IT!!!!!!!

I posted my fic for @diabolical-on-ao3!! The lyric I received was "I'm the knight, the solider who brings the fight at first light" (sampled from Hermitgang). It's a scriptstyle fic, that one could theoretically put on as a play, about Wels being insomnia'd by Hels.

It's short and sweet, but I'm proud that I did it. Everyone applaud now it took all of my ADHD strength to complete

[megabuild]

i enjoy how you write like a stageplay… it does things to me

SMOOCHES!! i hope i can get back to writing prose someday but in the meantime im having fun with doing little scriptstyle scraps it comes a lot more naturally to me

[supercoloneldruid]

does anybody in this fandom write scriptstyle fics or should I uhh do that myself.

[pinkplantmakesstuff]

I really wanna write stuff involving other people's characters but I'm super wary about either coming across as annoying or just writing the character really badly or in a way the other person doesn't like 😩

From the ground only the top part of the resulting rainbow is visible, the one in the shape of a multicolored arc. However, if we rise above the surface of the Earth we will realize that a rainbow continues below the horizon. That is why from the air we have a greater chance of witnessing a truly amazing phenomenon, a complete circular rainbow. This 360-degree rainbow was photographed from a helicopter flying, between a downpour that produced it and the rays of the Sun, over Cottesloe Beach, in Perth, Australia. Historical conception of the rainbow Throughout history and at different points in geography, an attempt has been made to explain the appearance of the rainbow in different ways. He could not give a scientific explanation because there was no scientific method as we know it today but at least they gave fantastic explanations. Illustration of the worlds according to Norse mythology with the Bifrost Irish mythology Without a doubt, the most "fantastic" and well-known conception he has of rainbows is that of the existence of a kind of gnome with a cauldron. According to Irish mythology, leprechauns are a species of gnomes that carry a pot full of gold. They are defined as cunning and greedy, and that is why the story goes that to protect their treasure they only come out of hiding when a rainbow appears. Leprechaun with a pot of gold at the base of a rainbow The children were told that if they were able to reach the point on earth from which the rainbow came out, they would meet one of these beings and be able to keep the gold. And, when we see a rainbow it gives us the feeling that it is like a colored ray that starts from a point on earth, as if someone were projecting it into the sky. The thing is, the rainbow is "generated" in our eyes (It is an optical effect), and whatever we walk we will never reach its base. (We will see later why). Newton's prism Optics was the object of study of many civilizations and as the years passed, advances in this branch of physics progressed. The study of the rainbow and the colors belongs to this branch, and it was not until approximately 1670 when Isaac Newton formulated a theory that related the visible or white light and the colors of the visible spectrum. Visible light is one of the bands of the electromagnetic spectrum, and within this band the colors appear, arranged in the same way as in the rainbow. The less energetic electromagnetic waves go below red and are called infrared, while the most energetic waves that go after violet are called ultraviolet. Newton's experiment Before Newton, Descartes already suspected the idea of ​​decomposing light into colors. However, he was not able to obtain more than two colors and did not know why it happened. To study the behavior of light Newton used a pair of glass prisms. In a darkened room where only a beam of light entered, he placed a prism in front of the beam, so that it passed through it and reflected the light on the opposite wall. He observed that the colors of the rainbow appeared on the wall in order one after another. Newton in his workshop with the prism experiment However, at this point there were two possibilities; Either the prism gave color to the light, or the light was the mixture of all the colors and the prism simply decomposed it. In order to reach a conclusion he realized in a second prism that he placed behind the light decomposed into colors. After moving the prism through each of the colors Furthermore, by meticulously placing a second prism he was able to mix all the colors and project a beam of white light. Two connected Newton prisms that decompose and unite colors Newton showed that what is normally known as visible or white light is really an indistinguishable union of waves of different frequencies, each associated with a color that our eye is capable of perceiving. How does Newton's prism work? The explanation is quite simple and is due to the difference in frequency of each of the colors + the refraction due to the change of medium. Refraction is the change in direction and speed that a wave experiences when passing from one medium to another with a different refractive index. Refraction of light in water This deviation in the direction of propagation is explained by means of Snell's law. On the other hand, and what really matters to us, is that the speed of penetration of light in a medium other than vacuum is related to the frequency of the wave. For a ray of light with an angle of incidence {\ displaystyle \ scriptstyle {\ theta _ {1}}} in the first medium, angle between the normal to the surface and the direction of propagation of the ray, we will have that the ray propagates in the second medium with an angle of refraction {\ displaystyle \ scriptstyle {\ theta _ {2}}} whose value is obtained by means of Snell's law: {\ Displaystyle n_ {1} \ \ operatorname {sin} \ theta_ {1} = n_ {2} \ \ operatorname {sin} \ theta_ {2} \,} Where {\ displaystyle n = \ frac {c} {v}} \ is the refractive index, which depends on the speed v of the wave in the medium. Snell's Law When a beam of white light passes from one medium to another, each color undergoes a slight deviation because each has a certain frequency. This phenomenon is known as light scattering. Newton's prism decomposing colors Formation of a rainbow The manifestation of the rainbow, as we have explained with Newton's prism, is due to a decomposition of white light into pure colors. Indeed, the drops of water that are still in the environment. That is why a rainbow only appears after it has rained a lot (Environment very loaded with drops of water) or there is a slight drizzle (Drops are falling but they do not reduce visibility or cover the sun). To understand the formation of the rainbow and understand why we will never be able to reach its base, it is necessary to be very clear that the rainbow is generated in our eye. It is an optical effect that depends on the observer due to the incidence of the rays. Nothing to do with an aurora borealis for example, where what you see are particles that exist as such. Animation of an aurora borealis The rainbow is generated in such a position that when we see it just behind us, the sun is located. The thing is, the sun's rays advance and enter the drops of water, producing refraction (the colors separate) and reflection (The ray returns to us). Refraction of light in water droplets What happens is that this ray with a circular shape due to its geometry goes directly to our eyes, and that is why from the earth we see the half circle or rainbow. Graphic formation of a rainbow Full rainbow of circular shape from an airplane View of a full rainbow from the sky It is a bit what happens with mirages, also caused by the refraction of hot air on the surface. THERE IS NOTHING there, it is an optical effect that is generated in our mind.

Cursive Calligraphy Alphabet: Lowercase Letters

Mastering the art of cursive calligraphy begins with learning the lowercase letters. By understanding the formation of each letter, you can develop a fluid and elegant cursive script. Let's explore the cursive calligraphy alphabet for lowercase letters to enhance your writing skills. The key to mastering cursive letter formation lies in practicing the basic strokes and understanding the proper technique for each letter. With lowercase cursive letters, you'll notice that many of them begin with an upward stroke. This creates the signature slant and graceful flow that cursive calligraphy is known for. When writing in cursive, maintain a consistent letter slant, ensuring that each letter leans slightly to the right. This creates a visually appealing and cohesive script. Remember to give each letter enough space to breathe, allowing for clear distinction between letters. Below is a table showcasing the cursive calligraphy alphabet for lowercase letters, along with the correct stroke order and direction for each letter. Practice writing these letters repeatedly to develop muscle memory and refine your cursive skills. Letter Stroke Order Example a 1. Upward stroke 2. Small loop to the left 3. Curve down and to the right 4. Cross in the middle b 1. Upward stroke 2. Loop to the right and down 3. Small loop to the left 4. Slant down and to the right c 1. Upward stroke 2. Curve to the right and down 3. Hook back to the left

d 1. Upward stroke 2. Loop to the right and down 3. Pull back and slant down to the right Continue practicing the remaining lowercase letters of the cursive calligraphy alphabet, such as e, f, g, and so on. With consistent practice and attention to detail, you'll soon be able to write in cursive with confidence and elegance.

Cursive Calligraphy Alphabet: Uppercase Letters

In cursive calligraphy, uppercase letters have their own unique flair and elegance. Mastering the formation of these uppercase letters will allow you to create stunning and sophisticated cursive script. Let's explore the uppercase cursive calligraphy alphabet and learn how to write each letter with precision and style. Uppercase Letter Formation When writing uppercase letters in cursive, it's important to pay attention to their distinct characteristics. Each letter has its own unique strokes and connections, which contribute to the overall aesthetics of your cursive script. Here is a guide to help you master the formation of uppercase cursive letters: Letter Formation A Start with a short upward stroke, then create a curve that extends downward to the baseline. Lift the pen, move to the right, and create a slanted stroke towards the baseline. B Begin with a small loop at the top, then form a curve that goes downward and loops back up to the top. Extend a vertical stroke from the loop to the baseline. C Start with a short upward stroke, then create a curve that extends downward, looping back up slightly towards the baseline. D Begin with a small loop at the top, then create a curve that goes downward and loops back up to the top, extending a vertical stroke from the loop to the baseline. Continue practicing the formation of each uppercase letter, paying attention to the flow and connections between strokes. With time and practice, you will develop a confident and consistent style in your uppercase cursive calligraphy. Remember to maintain a consistent slant and spacing between letters to ensure a harmonious appearance. Now that you have learned the formation of uppercase letters, you are one step closer to mastering the art of cursive calligraphy.

Tips for Improving Your Cursive Handwriting

If you're looking to enhance the aesthetic quality of your cursive handwriting, here are some tips and techniques to help you improve: - Find your optimal writing speed: Experiment with different writing speeds to find the pace that allows you to maintain consistency and control. Writing too fast can lead to sloppy letterforms, while writing too slowly can result in stiff and unnatural strokes. - Use guidelines: To achieve consistent letter slant and spacing, consider using guidelines as a reference. Whether you're using lined paper or creating your own guidelines, they can help guide the height and width of your letters for a more uniform cursive script. - Rotate your paper: Rotating your paper slightly can provide a more comfortable wrist position and improve the flow of your cursive writing. Experiment with different angles to find the one that works best for you. - Practice letter connectio

Choosing the Right Tools for Cursive Calligraphy

When it comes to cursive calligraphy, choosing the right tools is essential for achieving beautiful and elegant results. The right pen can make a significant difference in the flow and appearance of your cursive script. Here, we'll explore different types of pens that are suitable for cursive writing and discuss the importance of ink flow and pen pressure. One of the most popular choices for cursive calligraphy pens is the fountain pen. It provides a smooth and consistent ink flow, allowing for precise and graceful strokes. The fine nib of a fountain pen is ideal for creating thin and delicate lines, while a broader nib can add flair and variation to your cursive script. Experiment with different nib sizes to find the pen that suits your writing style. In addition to fountain pens, there are also brush pens specifically designed for cursive calligraphy. These pens have a flexible tip that mimics the brush strokes of traditional calligraphy brushes. Brush pens allow for greater control and versatility, allowing you to create both fine and bold lines in your cursive script. They are a popular choice for those looking to achieve a more expressive and dynamic style of cursive calligraphy. When using any type of pen for cursive calligraphy, it's important to consider pen pressure. Applying the right amount of pressure can greatly affect the appearance of your script. Lighter pressure creates thinner and lighter strokes, while heavier pressure produces thicker and darker lines. Experiment with different levels of pen pressure to add depth and contrast to your cursive calligraphy.

Lực là gì vật lý 6? Có bao nhiêu lực phổ biến nhất

Lực là gì vật lý 6? Vì sao lại có lực, phương và chiều của lực là gì? Có bao nhiêu lực hiện diện trong cuộc sống hàng ngày?

Định nghĩa lực là gì vật lý 6

Lực là một đại lượng véctơ đặc trưng cho tác dụng của vật này lên một vật khác làm vật bị biến dạng hoặc tạo ra gia tốc cho vật.

Đặc điểm của lực

Đơn vị: N (Niutơn)

Ký hiệu: F

Gốc tại điểm đặt lực

Độ dài của lực tỉ lệ với cường độ lực theo một tỉ lệ cho trước

Phương, chiều là phương chiều của lực.

Lực đàn hồi

Lực đàn hồi là một lực tác dụng lên lò xo khiến nó khôi phục lại trạng thái ban đầu, một lò xo lí tưởng được xem là không có ma sát, không bị đứt gãy hay không có khối lượng, có thể giãn vô hạn.

Lực đàn hồi là lực tỉ lệ với độ dịch chuyển của lò xo.

Những lò xo này sẽ bị nén lại khi khi có tác dụng của lực đẩy, hay bị kéo dài khi có lực kéo, lực này tỉ lệ với độ dịch chuyển của lò xo từ vị trí cân bằng của nó. Mối quan hệ tuyến tính này được Robert Hooke miêu tả vào năm 1676 qua định luật Hooke.

Lực ma sát

Không ai nhận ra lực hấp dẫn là một lực phổ quát cho đến khi Isaac Newton nghiên cứu về nó. Trước đó, xu hướng các vật rơi xuống mặt đất không được hiểu là có sự liên quan đến chuyển động của các thiên thể.

Một nghiên cứu đặc tính của các vận ra rơi do Galileo thí nghiệm đã miêu tả gia tốc của 1 vật rơi tư do là hằng số và độc lập với khối lượng của vật rơi.

Ngày nay, gia tốc do lực hấp dẫn về phía bề mặt trái đất được ký hiệu là {\displaystyle \scriptstyle {\vec {g}}} {\displaystyle \scriptstyle {\vec {g}}}, và có độ lớn đo được là khoảng 9,81met/giây bình phương (giá trị này có thể thay đổi tùy vào vị trí và đo tại mực nước biển) hướng về tâm trái đất.

Điều này có nghĩa là lực hấp dẫn tác động lên mọi vật thể tại bề mặt của trái đất  có tỉ lệ trực tiếp với khối lượng của vật thể đó.

Phương và chiều của lực:

Mọi vật đều có phương và chiều khác nhau.

Mỗi một vật sẽ có phương và chiều xác định như:

Gió tác dụng 1 lực đẩy lên cánh buồm, lực này có chiều từ trái qua phải và có phương nằm ngang.

Viên phấn sẽ bị trái đất tác dụng 1 lực hút, lực này có chiều từ trên xuống và có phương thẳng đứng.

Hai lực cân bằng:

Một vật đứng yên chịu tác dụng của 2 lực cân bằng thì sẽ tiếp tục đứng yên(2 lực cân bằng là 2 lực có sức mạnh bằng nhau, có cùng phương trên cùng 1 đường thẳng nhưng có chiều ngược lại với cùng 1 vật).

Ví dụ: cái ly đặt trên bàn sẽ đứng yên trên bàng vì có 2 lực cân bằng là :

Lực nâng của mặt bàn có chiều từ dưới lên, phương thẳng đứng.

Lực hút của trái đất có chiều từ trên xuống, phương thẳng đứng.

Hy vọng bài viết trên đã giúp các em hiểu rõ được lực là gì trong vật lý 6, chúc các em có thêm kiến thức hỗ trợ cho việc học của mình thật tốt.

擬交差(avoided crossing、しばしば"intended crossing"と誤記される)は、エルミート行列の固有値がN個の実数のパラメータに依存するとき、N-2次元以上の多様体上でない限り交差することができない現象である。例えば二原子分子の場合、結合距離という1つのパラメータにしか依存しないため、同じ対称性を持った状態に対するエネルギー固有値は交差することができない。三原子分子では、1点で交差することができる。(円錐型交差、en:conical intersection)

これは、量子化学で特に重要である。ボルン-オッペンハイマー近似においては、核の座標を固定して分子の電子ハミルトニアンの対角化を行う。核の座標の関数として得られた固有値は、断熱ポテンシャル曲面となるが、ちょうど擬交差をしている付近で核が運動すると、断熱状態間の遷移が起こりやすい。
