This is a really cool game to watch. It's simple enough to understand so far since it's just light, mirrors, and glass, plus its simplistic style with a splash of colour is visually appealing. I'd like to see more of this, or at least games in this style.

They're glass blocks, complete with "least action" of the path to get to the end the fastest, and a "complete internal refraction" range of angles, that's clever. :)

[@dailyyy5979]

what happened on the glass is called refraction, when light passes through a medium with a different refractive index, it loses some of its energy, and is bended

[@danielyuan9862]

Idk if "losing energy" is correct, because after the light leaves the glass, it's back to normal.

[@danielyuan9862]

Maybe "travels slower" is more accurate.

[@Big_Red1]

@@danielyuan9862 Kinda, in a roundabout way. Basically the photons enter the medium then hits an atom and is re-emitted at C, then hits another atom and is re-emitted, etc. Repeat until it exits. This emission takes a little bit of time which is where the slow down occurs, but in between hitting an atom, the light is traveling at C.

This is such a Tyler game, I could watch two straight weeks of this

[@YellowEllo]

Glass rules: 1. light always leaves from the angle it entered 2. When it enters it bends towards the normal, this makes the light move to other locations on the glass but still leave at the same angle. 3. If the light hits at a large enough angle on the back of the glass it will reflect at the same angle.

[@asher879]

Sleep? What's that?

[@KubickQ]

@@asher879 Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep,[1] and reduced interactions with surroundings.[2] It is distinguished from wakefulness by a decreased ability to react to stimuli, but more reactive than a coma or disorders of consciousness, with sleep displaying different, active brain patterns. Sleep occurs in repeating periods, in which the body alternates between two distinct modes: REM sleep and non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual paralysis of the body. A well-known feature of sleep is the dream, an experience typically recounted in narrative form, which resembles waking life while in progress, but which usually can later be distinguished as fantasy. During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems;[3] these are vital processes that maintain mood, memory, and cognitive function, and play a large role in the function of the endocrine and immune systems.[4] The internal circadian clock promotes sleep daily at night. The diverse purposes and mechanisms of sleep are the subject of substantial ongoing research.[5] Sleep is a highly conserved behavior across animal evolution.[6] Humans may suffer from various sleep disorders, including dyssomnias such as insomnia, hypersomnia, narcolepsy, and sleep apnea; parasomnias such as sleepwalking and rapid eye movement sleep behavior disorder; bruxism; and circadian rhythm sleep disorders. The use of artificial light has substantially altered humanity's sleep patterns.[7]

​@@KubickQ Furthermore, Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body - from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity.Sleep science has developed significantly in the past 20 years, providing growing insight about how sleep works, why it’s important, and the ways that it can be disrupted. Despite this advancing science, it remains common to encounter misinformation about sleep that is spread online, on social media, or by word-of-mouth. Some of this false information becomes repeated so often that it becomes a widely held myth. Even though these sleep myths are contrary to scientific evidence, they are often believed and can lead to poor sleep habits and insufficient sleep. In 2019, the National Sleep Foundation gathered a panel of experts to identify the most prominent and problematic sleep myths1. Reviewing these and other myths is an opportunity to learn the facts, set the record straight, and find ways to help get the sleep that you need. Sleep is an important part of your daily routine-you spend about one-third of your time doing it. Quality sleep - and getting enough of it at the right times -- is as essential to survival as food and water. Without sleep you can’t form or maintain the pathways in your brain that let you learn and create new memories, and it’s harder to concentrate and respond quickly. Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake. Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body - from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity. Sleep is a complex and dynamic process that affects how you function in ways scientists are now beginning to understand. This booklet describes how your need for sleep is regulated and what happens in the brain during sleep. Is Sleep Paralysis a Symptom of a Serious Problem? What Is Sleep Paralysis? Sleep paralysis is a feeling of being conscious but unable to move. It occurs when a person passes between stages of wakefulness and sleep. During these transitions, you may be unable to move or speak for a few seconds up to a few minutes. Some people may also feel pressure or a sense of choking. Sleep paralysis may accompany other sleep disorders such as narcolepsy. Narcolepsy is an overpowering need to sleep caused by a problem with the brain's ability to regulate sleep. Sleep researchers conclude that, in most cases, sleep paralysis is simply a sign that your body is not moving smoothly through the stages of sleep. Rarely is sleep paralysis linked to deep underlying psychiatric problems. Over the centuries, symptoms of sleep paralysis have been described in many ways and often attributed to an "evil" presence: unseen night demons in ancient times, the old hag in Shakespeare's Romeo and Juliet, and alien abductors. Almost every culture throughout history has had stories of shadowy evil creatures that terrify helpless humans at night. People have long sought explanations for this mysterious sleep-time paralysis and the accompanying feelings of terror. Sleep is a complex and dynamic process that affects how you function in ways scientists are now beginning to understand. This booklet describes how your need for sleep is regulated and what happens in the brain during sleep. Is Sleep Paralysis a Symptom of a Serious Problem? When Does Sleep Paralysis Usually Occur? Sleep paralysis usually occurs at one of two times. If it occurs while you are falling asleep, it's called hypnagogic or predormital sleep paralysis. If it happens as you are waking up, it's called hypnopompic or postdormital sleep paralysis. What Happens With Hypnagogic Sleep Paralysis? As you fall asleep, your body slowly relaxes. Usually you become less aware, so you do not notice the change. However, if you remain or become aware while falling asleep, you may notice that you cannot move or speak. What Happens With Hypnopompic Sleep Paralysis? During sleep, your body alternates between REM (rapid eye movement) and NREM (non-rapid eye movement) sleep. One cycle of REM and NREM sleep lasts about 90 minutes. NREM sleep occurs first and takes up to 75% of your overall sleep time. During NREM sleep, your body relaxes and restores itself. At the end of NREM, your sleep shifts to REM. Your eyes move quickly and dreams occur, but the rest of your body remains very relaxed. Your muscles are "turned off" during REM sleep. If you become aware before the REM cycle has finished, you may notice that you cannot move or speak. the natural, easily reversible periodic state of many living things that is marked by the absence of wakefulness and by the loss of consciousness of one's surroundings, is accompanied by a typical body posture (such as lying down with the eyes closed), the occurrence of dreaming, and changes in brain activity and physiological functioning, is made up of cycles of non-REM sleep and REM sleep, and is usually considered essential to the restoration and recovery of vital bodily and mental functions 2: a state resembling sleep: such as a: a state of torpid inactivity b: DEATH put a pet cat to sleep also : TRANCE, COMA c: the closing of leaves or petals especially at night d: a state marked by a diminution of feeling followed by tingling my foot's gone to sleep e: the state of an animal during hibernation 3a: a period spent sleeping b: NIGHT c: a day's journey 4: crusty matter present in the corner of an eye upon awakening Edit: I have been enlightned pogchamp

[@alansmithee419]

6:45 Hey, physics student here. Basically the light goes "argh wtf, glass!?" and gets scared. This causes it to bow to its new overlord, which is seen as a kink in the beam. The light then immediately rebels and tries to escape the glass. If the light is at too shallow an angle when it makes one of these attempts it won't have the confidence to keep going, and will turn around. Only on a direct enough path will it not have time to change its mind on its way out. The failure to leave is seen as internal reflection. Captors with high refractive indexes, like diamonds, are good at manipulating the light into developing Stockholm syndrome, making it not wish to leave, instead bouncing around inside much more than normal before realising what's happened and eventually leaving. This is why diamonds sparkle. Bastards.

[@indigoecho9016]

Thank you - assassinating the character of translucent objects really helped me learn this better XD

[@alansmithee419]

@@indigoecho9016 You know when you hit something with a hard object and you get hand shock? Translucent objects do that to light upon its entry. The light just goes "bwuhwuhwuhwuhwuh" (onomatopoeia) as it impacts the boundary of the translucent object, and it becomes shaken out of focus. Needless to say light does not have a good time of anything unless its left to do its own thing travelling through vacuums. This is the only time it's truly content.

[@rzezzy1]

Vocab time: When the laser bounces around INSIDE of a refracting lens, that's called Total Internal Reflection. It happens when a ray of light tries to leave a dense medium, but does so in a direction too nearly parallel to the surface.

[@danielyuan9862]

About the refraction idea, I believe there is this theorem called Snell's theorem. You can look it up, but the one thing about Snell's theorem is that light indeed always leave a piece of glass at the same angle as the angle at which they entered it.

[@CB-lh4ph]

would be a cool concept in the future if they add different beam strengths, then depending on the angle you approach glass you can split a beam into various percentages, or totally internally reflect a beam to maintain all of its strength

7:10 reflection and refraction in difrent mideum from air to glass

[@smokey3764]

When the light reflects through the glass it's called total internal reflection, and it happens when the angle of incidence of the light is bigger than the ratio of the ratio of the two refractive indexes of the material. It only happens when at the boundary of going into a lower refractive index (and in the case of 6:50 the glass is the material with the higher refractive index and the air has a lower one)

This reminds me so much of the puzzles in the (I think) Earth Temple in The Legend of Zelda: The Windwaker. I love it.

[@BigDBrian]

so for the glass, it seems that, ignoring the visuals on the inside, there's two options. The light comes out the opposite side in the same direction as it came in, or it comes out the opposite side but mirrored. Which of these occurs depends on how many times the light bounces off the remaining sides. (odd or even)

[@Sauspreme]
