just go with the flow

[escafeism]

minsan nga, sabi ng iba, sumakay ka na lang. just go with the flow, ika nga.

kasi minsan, kung ano na yung nakatakdang mangyari, eh yun na yun. kaya naman dapat wag na nating pakialaman pa baka kung anong disaster lang ang mangyari. nevertheless, i am not saying na all the time eh you will go with the flow na lang, hmp! may utak ka dude! gagamitin mo utak mo para mag-isip kung ano ba yung mas makakabuti sa’yo. kaya hindi sa lahat ng pagkakataon eh magpapadala ka na lang sa takbo ng buhay. paminsan minsan lang yan ha, yung tipong hahayaan mo kung saan ka dadalhin ng hangin, ng panahon, ng tadhana. pero sa oras na makita mong iba na ang kahahantungan na para bang napapakambyo na sa kaliwa at maling daan ang takbo ng buhay mo, edi tsaka ka umakto at kumilos. basta dapat lagi kang mag-isip kung tama pa ba yung mapupuntahan mo.

May the Four Forces Be With You!

May the force be with you? Much to learn you still have, padawan. In our universe it would be more appropriate to say, “May the four forces be with you.”

There are four fundamental forces that bind our universe and its building blocks together. Two of them are easy to spot — gravity keeps your feet on the ground while electromagnetism keeps your devices running. The other two are a little harder to see directly in everyday life, but without them, our universe would look a lot different!

Let’s explore these forces in a little more detail.

Gravity: Bringing the universe together

If you jump up, gravity brings you back down to Earth. It also keeps the solar system together … and our galaxy, and our local group of galaxies and our supercluster of galaxies.

Gravity pulls everything together. Everything, from the bright centers of the universe to the planets farthest from them. In fact, you (yes, you!) even exert a gravitational force on a galaxy far, far away. A tiny gravitational force, but a force nonetheless.

Despite its well-known reputation, gravity is actually the weakest of the four forces. Its strength increases with the mass of the two objects involved. And its range is infinite, but the strength drops off as the square of the distance. If you and a friend measured your gravitational tug on each other and then doubled the distance between you, your new gravitational attraction would just be a quarter of what it was. So, you have to be really close together, or really big, or both, to exert a lot of gravity.

Even so, because its range is infinite, gravity is responsible for the formation of the largest structures in our universe! Planetary systems, galaxies and clusters of galaxies all formed because gravity brought them together.

Gravity truly surrounds us and binds us together.

Electromagnetism: Lighting the way

You know that shock you get on a dry day after shuffling across the carpet? The electricity that powers your television? The light that illuminates your room on a dark night? Those are all the work of electromagnetism. As the name implies, electromagnetism is the force that includes both electricity and magnetism.

Electromagnetism keeps electrons orbiting the nucleus at the center of atoms and allows chemical compounds to form (you know, the stuff that makes up us and everything around us). Electromagnetic waves are also known as light. Once started, an electromagnetic wave will travel at the speed of light until it interacts with something (like your eye) — so it will be there to light up the dark places.

Like gravity, electromagnetism works at infinite distances. And, also like gravity, the electromagnetic force between two objects falls as the square of their distance. However, unlike gravity, electromagnetism doesn’t just attract. Whether it attracts or repels depends on the electric charge of the objects involved. Two negative charges or two positive charges repel each other; one of each, and they attract each other. Plus. Minus. A balance.

This is what happens with common household magnets. If you hold them with the same “poles” together, they resist each other. On the other hand, if you hold a magnet with opposite poles together — snap! — they’ll attract each other.

Electromagnetism might just explain the relationship between a certain scruffy-looking nerf-herder and a princess.

Strong Force: Building the building blocks

The strong force is where things get really small. So small, that you can’t see it at work directly. But don’t let your eyes deceive you. Despite acting only on short distances, the strong force holds together the building blocks of the atoms, which are, in turn, the building blocks of everything we see around us.

Like gravity, the strong force always attracts, but that’s really where their similarities end. As the name implies, the force is strong with the strong force. It is the strongest of the four forces. It brings together protons and neutrons to form the nucleus of atoms — it has to be stronger than electromagnetism to do it, since all those protons are positively charged. But not only that, the strong force holds together the quarks — even tinier particles — to form those very protons and neutrons.

However, the strong force only works on very, very, very small distances. How small? About the scale of a medium-sized atom’s nucleus. For those of you who like the numbers, that’s about 10-15 meters, or 0.000000000000001 meters. That’s about a hundred billion times smaller than the width of a human hair! Whew.

Its tiny scale is why you don’t directly see the strong force in your day-to-day life. Judge a force by its physical size, do you? 

Weak Force: Keeping us in sunshine

If you thought it was hard to see the strong force, the weak force works on even smaller scales — 1,000 times smaller. But it, too, is extremely important for life as we know it. In fact, the weak force plays a key role in keeping our Sun shining.

But what does the weak force do? Well … that requires getting a little into the weeds of particle physics. Here goes nothing! We mentioned quarks earlier — these are tiny particles that, among other things, make up protons and neutrons. There are six types of quarks, but the two that make up protons and neutrons are called up and down quarks. The weak force changes one quark type into another. This causes neutrons to decay into protons (or the other way around) while releasing electrons and ghostly particles called neutrinos.

So for example, the weak force can turn a down quark in a neutron into an up quark, which will turn that neutron into a proton. If that neutron is in an atom’s nucleus, the electric charge of the nucleus changes. That tiny change turns the atom into a different element! Such reactions are happening all the time in our Sun, giving it the energy to shine.

The weak force might just help to keep you in the (sun)light.

All four of these forces run strong in the universe. They flow between all things and keep our universe in balance. Without them, we’d be doomed. But these forces will be with you. Always.

You're the worst 🤦‍♂️

[kcinoj]

are we the waiting <?>

[write-it-motherfuckers]

When you had told your friends that you were finally getting the chance to move out and get far away from your family, they were happy for you. When they found out where you would be moving to however, that joy quickly turned into fear. Suddenly, every single one of them was trying to convince you not to do it.

The apartment building was a reasonably nice place, neither top of the line, nor the worst of the worse. It was in a decent area, at an affordable price, and your new landlord had been blessedly understanding about holding the apartment for you, until you could arrive. There was only one thing that was a cause for concern.

You would be the Only human in the entire building.

Though the supernatural races had finally integrated fully with the mundane world a number of years ago, there was still some tensions that lingered from time to time. You’re friends likely wouldn’t have been so vocal if you had simply had a supernatural neighbour or two, as these days it was quite common. But the knowledge that you would be the only human in an apartment complex filled with the supernatural, was more than a little worrying. You would essentially be in their territory. 

Whilst you appreciated their concern, you held no such reservations, or at least not the same kind that they did. The only thing about their nature that concerned you, was whether you would accidentally offend any of them, having never really had a chance to learn about the other races, with how your family was. You knew what true evil looked like, had lived with it your whole life. You refused to judge any of them, simply based on their race.

Due to the distance, moving was done mostly by yourself, though your new landlord, a rather motherly old werewolf, insisted upon helping you once you arrived. Between the two of you, with her rather magnificent strength, despite her age, you managed to heave the few pieces of furniture you had, into your new apartment rather quickly. It was clear that she had been concerned by how little you owned, but thankfully she relented after a while, in favour of talking you through the paperwork.

Surprisingly, you found yourself settling in rather quickly, though you hadn’t seen all too much of your new neighbours, other than an overly friendly nature witch, who had gifted you a singing succulent as a housewarming gift. Your landlord had all but adopted you, and with how well soundproofed the whole building was, because of all the heightened senses, you didn’t even have to worry about disturbing anyone with your nightmares or the odd hours you kept.

At your request, the landlady had very kindly started to coach you on the rules and social etiquette of dealing with the other races, and a few days ago, you had finally fallen into a good groove at your new job. For the first time in your life, you were starting to feel safe and content, perhaps even happy. 

You could only hope that none of that would change, once you finally started meeting the rest of your neighbours. You had a feeling they were avoiding you, though you were too insecure to do anything about it. Only time would tell.

The curious case of the Runaway heart

Although there are no particles that are known to us to have negative mass, physicists in the 1950s( primarily Hermann Bondi, William B. Bonnor  and  Robert L. Forward ) explored the physics of what would happen if we had negative mass.

The most interesting case is when we have a positive and negative mass:

There is a push that repels the positive mass from the negative mass, and a pull that attracts the negative mass towards the positive one at the same time through eternity.

This is known as ‘runaway motion effect’ .

One bizarre consequence (among many others) of the runaway effect is that gas containing a mixture of positive and negative matter particles will have the positive matter portion increase in temperature without bound.

However, the negative matter portion gains negative temperature at the same rate without bounds but somehow mysteriously net temperature of the gas would still have not changed all this while. *

Just a random factoid that we thought we would share on this Valentine’s day. Have a great day!

A note on the Hydrogen spectrum

** This note was inspired from a comment on one of our previous post. Do check it out before you read this one.

The emission spectrum of atomic hydrogen is given by this amazing spectral series diagram:

Let’s take a closer look at only the visible portion of the spectrum i.e the Balmer series.

If a hydrogen lamp and a diffraction grating just happen to be with you, you can take a look at the hydrogen lamp through the diffraction grating, these lines are what you would see:

                                                      Source 

These are known emission lines and they occur when the hydrogen atoms in the lamp return to a state of lower energy from an excited energy state.

           Representation of emission and absorption using the Bohr’s model

Here’s another scenario that could also happen:

You have a bright source of light with a continuous spectrum and in between the source and the screen, you introduce a gas (here, sodium)

                              Source: Harvard Natural sciences

The gas absorbs light at particular frequencies and therefore we get dark lines in the spectrum.

This is known as absorption line. The following diagram summarizes what was told thus-far in a single image:

The absorption and emission spectrum for hydrogen look like so :

Stars and Hydrogen

One of the comments from the previous post was to show raw spectrum data of what was being presented to get a better visual aid.

Therefore,the following spectrum is a spectrum of a star taken from the Sloan Digital Sky Survey (SDSS)

                                 Plot of wavelength vs median-flux

Here’s the spectrum with all the absorption lines labelled:

                                               Source: SDSS

You can clearly see the Balmer series of hydrogen beautifully encoded in this spectrum that was taken from a star that is light-years away.

And astronomers learn to grow and love these lines and identify them immediately in any spectrum, for they give you crucial information about the nature of the star, its age, its composition and so much more.

Have a great day!

*If you squint your eyes a bit more you can find other absorption lines from other atoms embedded in the spectrum as well.
