To be honest, I should do this long time ago. And my English is still incompetence, so excuse me.

I don't know where to start. Really! Back then, before my higher-education, I did have problems. Coming-of-age problems,you see. There were too many of them, and I wasn't the genius of making right decision (You can tell that from my Chemistry graduation exam). To be frank, I made shitty decisons. After the problems was an entire year of mind-free, care-free lifestyle. Oh f#ck it, who am I kidding? I gave up. I did give up on my life. I did give up on myself. I didn't use drug or commit any crime, but I lost my motivation. My intention back then was to walk away, live like a driftwood, letting itself go with the flow of a river. No acquaintance, no family, be an useless piece of meat rotting day by day till the day the last piece of me become ash. That was my intention.

And then I was introduced to Her.

I don't know how to explain it. The feeling came very... suddenly. I saw her on a podcast. I was amazed by her drawing, her talent, her beauty. And with some help, I have a crush on her.

To be honest, having living for 18 years, I had have a crush on a few people before. And to a 18 year old teenager, that seemed pretty common.

But, the thing I hadn't have expected happened, I fell in love with her.

Yes, I know the world "Love" sounds like a big deal (Especially if you're Japanese : あい、すき。。。). But that might be the only way I can express this feeling. This isn't like the childish love, or the love of bunch of tweens/teens. This isn't the kind of love that exists just for you to tell your friends that "I have a girlfriend. We French kiss and bang everyday" and then have a high five and beers. No, no, no!

Everytime I see her, my heart races. As I care more about her, I admired her more. And the more of that, the more I want to be next to her, talk to her, get to know her. She gave me motivation, she is the reason I am still alive. The more I love her, the more I want myself to be worthy of her. Be able to met her has been my life goal since then. It's seemed like that I exist just to follow her. ( And due to the fact that her cat and I might share the same birthday, you can imagine how crazy the thing I had in my mind at that moment I figured it out)

And god knows how many crazy thing I have done, the thing that my old self would have killed me rather than do it (If there's a god). Since the podcast, I'm motivated. Sometimes to the point I thought I might be crazy. I assigned to the top tier technology university of my country. (But not the top tier class, in fact I might be regret choosing that class. Gosh it's expensive, and still barely recognised :v). I started to join the student community, even the support department of the student council. I have met other people, talented friends who is the same age as mine, but way more precious, famous, useful, energetic and appreciated, the elder from the higher class who has more experienced and talent. The life in university was sure something exciting to me. And i even hoped that i can entirely changed myself into an energetic, talented person, like the others.

But, sometime,I wondering about this choice I made.

And know, the freshman year of mine has ended, I can't really help myself doubt about myself more. My record isn't the best. It's nowhere near the high goal, it probably can't even reach the standard goal.

Social communication? At least I made some improvement, but it's still a long way to go for me to reach the point where I can easily talk to other people. Sometime, talking to others still make me feel like being tortured.

And don't forget the distraction for an entire year.

Also, money, family problems,...things come to me like a river. It always has, and sure it will continue to.

If it weren't for her, I probably would have given up, like the old day. For her, for myself, I still stand and continuing head toward. But, sometimes, I barely the the light at the end of the road. Sometimes, I wished that I could be with her right now, so that I can lie on her shoulder and cry, cry out all of my feeling, my anxiety, my hurt. But, if I can't make it now, I can't see her soon. And the time is running out.

She's now 28, soon she will be 30.She is now at the peak of the success and adoration. And it's really odd if she doesn't have a boyfriend. Guys in and out of her country is dying just to be the lucky guy. I really want her to be happy, to settle down, live a happy, successful life. But I want to be the lucky guy. I want to be the guy that everytime waking up, receiving phone calls from her, getting home, seeing her face, making dinner together, caring about each other, telling each other about our day, hugging cuddling, passionately kissing, wishing each other good night and falling asleep holding each other...things like that make me want to do better, to be better everyday, to be worthy of her.

(And the fantasy make me no longer feel depressed...Wow, this is actually work?)

So, I still have some year left, to improve myself, to have a guaranteed income, and to achieve my closet goal: graduate and then get to her as close as possible. It's gonna be rough. The light from the stars might not always shine the path. But if it's for my future with her, I shall walk on the desert of solitude,as long as I need.

For her, I will.

P/s: 悠木碧さん、I don't expect you to read this post, or aware of my existence. But as a person who truly adore you, I really wish you to be happy, successful, and always be adored by the people you love

Love you.

No, We Haven’t Solved The Drake Equation, The Fermi Paradox, Or Whether Humans Are Alone

“No amount of fancy probabilistic analysis can justify treating guesswork and wishful thinking as having any sort of scientific weight. Applying scientific techniques to an inherently unscientific endeavor, such as inventing estimates to unknowns about the Universe, doesn’t make it any more scientific. The opposite of knowledge isn’t ignorance; it’s the illusion of knowledge.

It’s still possible that life, and even intelligent life, is ubiquitous in our galaxy and the Universe. It’s also possible that one is common and one is uncommon, or that both are extraordinarily rare. Until we have more information, don’t be fooled by the headlines: these aren’t brilliant estimates or groundbreaking work. It’s guessing, in the absence of any good evidence. That’s no way to do science. In fact, until we have better evidence, it’s not science at all.”

There’s a new paper out that’s making some fantastic waves: Dissolving the Fermi Paradox. In it, the authors apply some probabilistic analysis to other estimates for the likelihoods of the parameters in the Drake equation, and come up with a value for the probability that we’re alone in the Universe. There’s just one problem: the input parameters are total garbage, and so the output parameters are garbage, too.

We have no idea whether humans are alone in the Universe. Embrace the possibilities, but don’t you dare pretend your so-called probabilities mean anything. They don’t.

Ask Ethan: Could The Energy Loss From Radiating Stars Explain Dark Energy?

“What happens to the gravity produced by the mass that is lost, when it’s converted by nuclear reactions in stars and goes out as light and neutrinos, or when mass accretes into a black hole, or when it’s converted into gravitational waves? […] In other words, are the gravitational waves and EM waves and neutrinos now a source of gravitation that exactly matches the prior mass that was converted, or not?”

For the first time in the history of Ask Ethan, I have a question from a Nobel Prize-winning scientist! John Mather, whose work on the Cosmic Microwave Background co-won him a Nobel Prize with George Smoot, sent me a theory claiming that when matter gets converted into radiation, it can generate an anti-gravitational force that might be responsible for what we presently call dark energy. It’s an interesting idea, but there are some compelling reasons why this shouldn’t work. We know how matter and radiation and dark energy all behave in the Universe, and converting one into another should have very straightforward consequences. When we take a close look at what they did, we can even figure out how the theory’s proponents fooled themselves.

Radiating stars and merging black holes do change how the Universe evolves, but not in a way that can mimic dark energy! Come find out how on this week’s Ask Ethan.

Einstein Wins Again! General Relativity Passes Its First Extragalactic Test

“For the first time, we’ve been able to perform a direct test of General Relativity outside of our Solar System and get solid, informative results. The ratio of the Newtonian potential to the curvature potential, which relativity demands be equal to one but where alternatives differ, confirms what General Relativity predicts. Large deviations from Einstein’s gravity, therefore, cannot happen on scales smaller than a few thousand light years, or for masses the scale of an individual galaxy. If you want to explain the accelerated expansion of the Universe, you can’t simply say you don’t like dark energy and throw Einstein’s gravity away. For the first time, if we want to modify Einstein’s gravity on galactic-or-larger scales, we have an important constraint to reckon with.”

For many of the greatest cosmic puzzles today, you can either add two new ingredients, dark matter and dark energy, or you can seek to modify Einstein’s theory of gravity. While Einstein’s General Relativity has been confirmed spectacularly under a wide variety of circumstances, the only robust tests that are independent of dark matter or dark energy assumptions occur on scales of the Solar System or smaller. That’s only for distances that are a tiny fraction of a light year, and for masses no bigger than the Sun, which should trouble you when you’re making inferences about galaxies, clusters, or the entire Universe! But thanks to a very fortunate galactic system  — a strong gravitational lens that is only 500 million light years distant  — we’ve been able to put Einstein’s theory of gravity to the test for galactic masses and distance scales in the thousands of light years.

Was there ever any doubt that Einstein would win again? Here’s what happened, and here’s what it means for alternative theories of gravity!

The universe that Stephen Hawking spent a lifetime studying now knows his voice.

Following Hawking’s death in March, the renowned British physicist, who had battled a debilitating degenerative motor neuron disease for decades, was remembered at a memorial service Friday at Westminster Abbey.

His ashes were buried between Charles Darwin and Isaac Newton and later covered with a gravestone — etched with an equation he used to teach the world about black holes.

But at the same time his ashes were lowered into the ground, his voice was beamed from Earth thousands of light-years away toward the nearest known black hole in the universe.

It was a “symbolic gesture,” his loved ones said, that finally let him travel into space.

Heat sinks

If you have explored the interior of your CPU then you might have noticed that there are these horizontal metal plates (called fins) many a times with a fan on top of the central or graphic processors.

They are called heat sinks/heat exchangers and are used to dissipate the heat generated by the processor to the surrounding.

The reason why they work is that according to the Fourier’s law, the heat dissipated is directly proportional to the cross sectional area.

And adding protrusions to the surface increases the net cross section area for exchanging the heat with the surrounding.

Cooking with a computer

In order to demonstrate the extent to which the processor would heat up, let’s remove the heat sink and place a piece of meat on it.

At such high temperatures where cooking a piece of meat becomes possible on a processor, you can be damn sure that the probability of the survival of a computer running without a heat sink is just  0. **

Have a great day!

Pick Your Favorite Findings From Fermi’s First Decade

The Fermi Gamma-ray Space Telescope has been observing some of the most extreme objects and events in the universe — from supermassive black holes to merging neutron stars and thunderstorms — for 10 years. Fermi studies the cosmos using gamma rays, the highest-energy form of light, and has discovered thousands of new phenomena for scientists.

Here are a few of our favorite Fermi discoveries, pick your favorite in the first round of our “Fermi Science Playoff.” 

Colliding Neutron Stars

In 2017, Fermi detected a gamma ray burst at nearly the same moment ground observatories detected gravitational waves from two merging neutron stars. This was the first time light and ripples in space-time were detected from the same source.

The Sun and Moon in Gamma Rays

In 2016, Fermi showed the Moon is brighter in gamma rays than the Sun. Because the Moon doesn’t have a magnetic field, the surface is constantly pelted from all directions by cosmic rays. These produce gamma rays when they run into other particles, causing a full-Moon gamma-ray glow.

Record Rare from a Blazar

The supermassive black hole at the center of the galaxy 3C 279 weighs a billion times the mass of our Sun. In June 2015, this blazar became the brightest gamma-ray source in the sky due to a record-setting flare.

The First Gamma-Ray Pulsar in Another Galaxy

In 2015, for the first time, Fermi discovered a gamma-ray pulsar, a kind of rapidly spinning superdense star, in a galaxy outside our own. The object, located on the outskirts of the Tarantula Nebula, also set the record for the most luminous gamma-ray pulsar we’ve seen so far.

A Gamma-Ray Cycle in Another Galaxy

Many galaxies, including our own, have black holes at their centers. In active galaxies, dust and gas fall into and “feed” the black hole, releasing light and heat. In 2015 for the first time, scientists using Fermi data found hints that a galaxy called PG 1553+113 has a years-long gamma-ray emission cycle. They’re not sure what causes this cycle, but one exciting possibility is that the galaxy has a second supermassive black hole that causes periodic changes in what the first is eating.

Gamma Rays from Novae

A nova is a fairly common, short-lived kind of explosion on the surface of a white dwarf, a type of compact star not much larger than Earth. In 2014, Fermi observed several novae and found that they almost always produce gamma-rays, giving scientists a new type of source to explore further with the telescope.

A Record-Setting Cosmic Blast

Gamma-ray bursts are the most luminous explosions in the universe. In 2013, Fermi spotted the brightest burst it’s seen so far in the constellation Leo. In the first three seconds alone, the burst, called GRB 130427A, was brighter than any other burst seen before it. This record has yet to be shattered.

Cosmic Rays from Supernova Leftovers

Cosmic rays are particles that travel across the cosmos at nearly the speed of light. They are hard to track back to their source because they veer off course every time they encounter a magnetic field. In 2013, Fermi showed that these particles reach their incredible speed in the shockwaves of supernova remains — a theory proposed in 1949 by the satellite’s namesake, the Italian-American physicist Enrico Fermi.

Discovery of a Transformer Pulsar

In 2013, the pulsar in a binary star system called AY Sextanis switched from radio emissions to high-energy gamma rays. Scientists think the change reflects erratic interaction between the two stars in the binary.

Gamma-Ray Measurement of a Gravitational Lens

A gravitational lens is a kind of natural cosmic telescope that occurs when a massive object in space bends and amplifies light from another, more distant object. In 2012, Fermi used gamma rays to observe a spiral galaxy 4.03 billion light-years away bending light coming from a source 4.35 billion light-years away.

New Limits on Dark Matter

We can directly observe only 20 percent of the matter in the universe. The rest is invisible to telescopes and is called dark matter — and we’re not quite sure what it is. In 2012, Fermi helped place new limits on the properties of dark matter, essentially narrowing the field of possible particles that can describe what dark matter is.

‘Superflares’ in the Crab Nebula

The Crab Nebula supernova remnant is one of the most-studied targets in the sky — we’ve been looking at it for almost a thousand years! In 2011, Fermi saw it erupt in a flare five times more powerful than any previously seen from the object. Scientists calculate the electrons in this eruption are 100 times more energetic than what we can achieve with particle accelerators on Earth.

Thunderstorms Hurling Antimatter into Space

Terrestrial gamma-ray flashes are created by thunderstorms. In 2011, Fermi scientists announced the satellite had detected beams of antimatter above thunderstorms, which they think are a byproduct of gamma-ray flashes.

Giant Gamma-Ray Bubbles in the Milky Way

Using data from Fermi in 2010, scientists discovered a pair of “bubbles” emerging from above and below the Milky Way. These enormous bubbles are half the length of the Milky Way and were probably created by our galaxy’s supermassive black hole only a few million years ago.

Hint of Starquakes in a Magnetar

Neutron stars have magnetic fields trillions of times stronger than Earth’s. Magnetars are neutron stars with magnetic fields 1,000 times stronger still. In 2009, Fermi saw a storm of gamma-ray bursts from a magnetar called SGR J1550-5418, which scientists think were related to seismic waves rippling across its surface.

A Dark Pulsar

We observe many pulsars using radio waves, visible light or X-rays. In 2008, Fermi found the first gamma-ray only pulsar in a supernova remnant called CTA 1. We think that the “beam” of gamma rays we see from CTA 1 is much wider than the beam of other types of light from that pulsar. Those other beams never sweep across our vision — only the gamma-rays.

10 Things: Calling All Pluto Lovers

June 22 marks the 40th anniversary of Charon’s discovery—the dwarf planet Pluto’s largest and first known moon. While the definition of a planet is the subject of vigorous scientific debate, this dwarf planet is a fascinating world to explore. Get to know Pluto’s beautiful, fascinating companion this week.

1. A Happy Accident

Astronomers James Christy and Robert Harrington weren’t even looking for satellites of Pluto when they discovered Charon in June 1978 at the U.S. Naval Observatory Flagstaff Station in Arizona – only about six miles from where Pluto was discovered at Lowell Observatory. Instead, they were trying to refine Pluto’s orbit around the Sun when sharp-eyed Christy noticed images of Pluto were strangely elongated; a blob seemed to move around Pluto. 

The direction of elongation cycled back and forth over 6.39 days―the same as Pluto’s rotation period. Searching through their archives of Pluto images taken years before, Christy then found more cases where Pluto appeared elongated. Additional images confirmed he had discovered the first known moon of Pluto.

2. Forever and Always

Christy proposed the name Charon after the mythological ferryman who carried souls across the river Acheron, one of the five mythical rivers that surrounded Pluto’s underworld. But Christy also chose it for a more personal reason: The first four letters matched the name of his wife, Charlene. (Cue the collective sigh.)

3. Big Little Moon

Charon—the largest of Pluto’s five moons and approximately the size of Texas—is almost half the size of Pluto itself. The little moon is so big that Pluto and Charon are sometimes referred to as a double dwarf planet system. The distance between them is 12,200 miles (19,640 kilometers).

4. A Colorful and Violent History

Many scientists on the New Horizons mission expected Charon to be a monotonous, crater-battered world; instead, they found a landscape covered with mountains, canyons, landslides, surface-color variations and more. High-resolution images of the Pluto-facing hemisphere of Charon, taken by New Horizons as the spacecraft sped through the Pluto system on July 14 and transmitted to Earth on Sept. 21, reveal details of a belt of fractures and canyons just north of the moon’s equator.

5. Grander Canyon

This great canyon system stretches more than 1,000 miles (1,600 kilometers) across the entire face of Charon and likely around onto Charon’s far side. Four times as long as the Grand Canyon, and twice as deep in places, these faults and canyons indicate a titanic geological upheaval in Charon’s past.

6. Officially Official

In April 2018, the International Astronomical Union—the internationally recognized authority for naming celestial bodies and their surface features—approved a dozen names for Charon’s features proposed by our New Horizons mission team. Many of the names focus on the literature and mythology of exploration.

7. Flying Over Charon

This flyover video of Charon was created thanks to images from our New Horizons spacecraft. The “flight” starts with the informally named Mordor (dark) region near Charon’s north pole. Then the camera moves south to a vast chasm, descending to just 40 miles (60 kilometers) above the surface to fly through the canyon system.

8. Strikingly Different Worlds

This composite of enhanced color images of Pluto (lower right) and Charon (upper left), was taken by New Horizons as it passed through the Pluto system on July 14, 2015. This image highlights the striking differences between Pluto and Charon. The color and brightness of both Pluto and Charon have been processed identically to allow direct comparison of their surface properties, and to highlight the similarity between Charon’s polar red terrain and Pluto’s equatorial red terrain.

9. Quality Facetime

Charon neither rises nor sets, but hovers over the same spot on Pluto’s surface, and the same side of Charon always faces Pluto―a phenomenon called mutual tidal locking.

10. Shine On, Charon

Bathed in “Plutoshine,” this image from New Horizons shows the night side of Charon against a star field lit by faint, reflected light from Pluto itself on July 15, 2015.
