![]() Observation plays a key role throughout the entire scientific investigation process, not only in the phase of data collection. Progression from everyday to expert scientific skills of observation should be a more central focus of science teaching by providing extended time for careful observations, teachers’ encouragements, shared noticing and conversations between teachers and children, peer interaction, sketching and drawing, sculpture, diary-writing, and asking questions (see for example Eberbach & Crowley, 2017). Just as children’s intuitive (spontaneous) concepts are gradually refined and replaced by scientific concepts (for instance, not all organisms that fly and have beaks are birds), intuitive observations are replaced with more selective, sophisticated, and theory-driven observations that lead to the development of scientific explanations of natural phenomena (Tomkins & Tunnicliffe, 2007). ![]() Initially, children start observing using multiple senses simultaneously – sight, sound, smell, touch, taste – and gradually, step by step, they develop simple explanations of observations and complex interpretations of the world around them. Observation is an important initial skill in the early years that helps children find and organise patterns in the observed natural world. Observations sometimes can be very specific, developed within a disciplinary framework, such as in ornithology: learning how to recognize bird songs, silhouettes and flying patterns. Observation skills are more than ‘just looking’ at things or ‘just seeing’ things. However, are their observations trivial and effortless, or do we, as teachers or parents, need to encourage and facilitate their observational skills? Children’s observations and investigations of the local environment enable them to identify and answer questions that trigger further curiosity. Young children’s fascination with the world around them is something education must capitalise on to develop their ‘invisible glasses’ (that is, their worldview) and foster scientific process skills. Children are seekers of explanations to make sense of their experiences with nature. This beautiful quote from the Slovenian writer Feri Lainšček captures the essence of why educators should devote time to developing children’s observational skills starting in early childhood. She just knows because there is something about that frog that she has picked up subconsciously because she is a very good observer that she can actually work that out.‘In that earliest childhood, we get those invisible glasses through which we look at the world all our lives, and these glasses color our views.’ A very good example, I think, is that my student who has been working on the sex identification has become such a good observer that she can look at a frog and think, “That’s a female.” And we haven’t been able to scientifically quantify how she knows that. ![]() It does become critical, particularly when you’re working with frogs. What can I see? What can I hear? What can I feel? The things we do like taking measurements and handling animals – it’s a chance to just step back a wee bit and say, well, let the animal speak to me. So it’s a chance to reflect, to pause, if you like. So I would say that most research scientists are usually very observant people. I think observation is… A key element that drives you into wanting to do research is that you make an observation and you think that’s a bit strange, I didn’t notice that last time. Observation is a critical part of being a scientist, and observation is not just about what you can see with your eyes, but for me, it’s using all your senses and letting the animal speak to you.

The slow ascent is somehow made more entertaining by the group’s dependence the super-strong Konechek, both through his cavalier attitude and through Amos’ use of the nickname “Tiny.” Even though the eventual betrayal is unsurprising, the battle leading to Amos throwing the prisoner down the elevator shaft was everything we could ask for in a fight scene. Very effective storytelling!īut of course all eyes in this episode of The Expanse are on Amos as he extracts himself and Clarissa from the underground prison. Despite the fact that Cyn defends Naomi against Marco’s power games, his attempts to take her mind off of her imprisonment fail spectacularly but also give Naomi the opportunity she needs to let Holden know where she is. Marco is clearly very manipulative of his son, and it’s likely he was just as controlling of Naomi in the past. The fact that Naomi inferred Marco’s use of her Augustin Gamarra code is quite telling of her past with the extremists. Holden’s small progress was made more thrilling by this narrow escape, and without that moment of drama, all we would have is his fruitless interrogation, his uncovering of Zmeya’s flight plan, and the fact that Bull will be accompanying him as pilot. ![]() ![]() Interesting timing, that! Marco’s ships are either very close to Tycho or her transmission delay was just short enough to arrive just in time - an understandable narrative allowance for The Expanse as a TV show rather than a book. It may not have been the best idea to take a knife to the bridge, but Filip’s interference (“I saved your life!”) gave her the hint she needed to warn Holden about the sabotage onboard the Rocinante. We can almost feel her hunger and discomfort as she navigates the ship, supposedly free to go where she wishes. Naomi’s confinement, however, has given us some of the best acting from Dominique Tipper we’ve seen in The Expanse. Alex is at his best when piloting, and besides confirming with Bobbie that the Martian military has been selling frigates to the Belters (something we kind of already knew), it was nice to see the Razorback in action. Not that we would wish for them to dump their core and be drifting in space, but their storyline was in danger of becoming too procedural and expository. With a cliffhanger ending and lots of unresolved questions, The Expanse is still one of the best sci-fi shows on TV but season 5 just misses the mark of excellence that its predecessors achieved so effortlessly. In the case of Alex and Bobbie, it was a desperately needed boost. While it’s not a disappointment, the show is also not quite as expansive as it could have been. In this way, the show is able to maintain tension in the background even as drama unfolds on Earth and aboard Marco’s ship. Ironically, Season 5 feels more cohesive than last season, even though the characters are more separated than they’ve ever been, because they’re united by their reactions to world-shaking. ![]() Naomi and Amos take center stage in “Down and Out,” but the episode also expertly foreshadows future confrontations and highlights the consequences for going after conspirators, whether with Holden’s aborted pursuit of the Zmeya or Alex’s narrow escape from the Barkeith. There’s a sense in The Expanse season 5 that with all of the characters separated, each one is going to get their chance to shine. This The Expanse review contains spoilers. Only once signaling has been successfully completed can the true process of opening the WebRTC peer connection begin. Media capability negotiation: what codecs and media data formats can the peers understand? These need to be agreed upon before the WebRTC session can begin.Information needed in order to set up the connection: the IP addressing and port information needed for the peers to be able to talk to one another.Control messages used to set up, open, and close the communication channel, and to handle errors.There are three basic types of information that need to be exchanged during signaling: It'd be very high latency but it could be done. One peer can output a data object that can be printed out, physically carried (on foot or by carrier pigeon) to another device, entered into that device, and a response then output by that device to be returned on foot, and so forth, until the WebRTC peer connection is open. ![]() It's also worth noting that the channel for performing signaling doesn't even need to be over the network. You could even use email as the signaling channel. In order to exchange signaling information, you can choose to send JSON objects back and forth over a WebSocket connection, or you could use XMPP or SIP over an appropriate channel, or you could use XMLHttpRequest over HTTPS with polling, or any other combination of technologies you can come up with. Since WebRTC doesn't live in a vacuum, there is likely other connectivity in play, so it makes sense to avoid having to add additional connection channels for signaling if an existing one can be used. In particular, if a developer already has a method in place for connecting two devices, it doesn't make sense for them to have to use another one, defined by the specification, just for WebRTC. Why, you may wonder, is something fundamental to the process of establishing a WebRTC connection left out of the specification? The answer is simple: since the two devices have no way to directly contact each other, and the specification can't predict every possible use case for WebRTC, it makes more sense to let the developer select an appropriate networking technology and messaging protocol. The most important thing to know about the signaling process for WebRTC: it is not defined in the specification. Signaling is the process of sending control information between two devices to determine the communication protocols, channels, media codecs and formats, and method of data transfer, as well as any required routing information. You need to look up her address and include it on the package, or she'll wind up wondering why you forgot her birthday again. This is like trying to mail a package to your friend Michelle by labeling it "Michelle" and dropping it in a mailbox when you don't know her address. Even though you know who you want to talk to, you don't necessarily know how to reach them or even what their address is. For developers trying to do peer-to-peer networking, this introduces a conundrum: without a unique identifier for every user device, it's not possible to instantly and automatically know how to connect to a specific device on the internet. The problem for users is that each individual computer on the internet no longer necessarily has a unique IP address, and, in fact, each device's IP address may change not only if they move from one network to another, but if their network's address is changed by NAT and/or DHCP. Network Address Translation ( NAT) is a standard which supports this address sharing by handling routing of data inbound and outbound to and from devices on a LAN, all of which are sharing a single WAN (global) IP address. But they realized that it would take longer to complete the transition than 32-bit addresses would last, so other smart people came up with a way to let multiple computers share the same 32-bit IP address. It's so big that years ago, smart people saw how big it was, how fast it was growing, and the limitations of the 32-bit IP addressing system, and realized that something had to be done before we ran out of addresses to use, so they started working on designing a new 64-bit addressing system. ![]()

As the middle ear bones vibrate, they vibrate the cochlea, which contains fluid. This protective reaction can also be triggered by your own voice, so that humming during a fireworks display, for example, can reduce noise damage.įigure 14.12 shows the middle and inner ear in greater detail. They react to intense sound in a few milliseconds and reduce the force transmitted to the cochlea. ![]() Two muscles in the middle ear protect the inner ear from very intense sounds. The lever system of the middle ear takes the force exerted on the eardrum by sound pressure variations, amplifies it and transmits it to the inner ear via the oval window. The middle ear converts sound into mechanical vibrations and applies these vibrations to the cochlea. The outer ear, or ear canal, carries sound to the eardrum protected inside of the ear. The body part normally referred to as the ear is technically called the pinna.įigure 14.11 The illustration shows the anatomy of the human ear. The ear converts sound waves into electrical nerve impulses, similar to a microphone.įigure 14.11 shows the anatomy of the ear with its division into three parts: the outer ear or ear canal the middle ear, which runs from the eardrum to the cochlea and the inner ear, which is the cochlea itself. The sound wave that hits our ear is a pressure wave. The way we hear involves some interesting physics. The perception of frequency is called pitch, and the perception of intensity is called loudness. Sounds below 20 Hz are called infrasound, whereas those above 20,000 Hz are ultrasound. You may have noticed that dogs respond to the sound of a dog whistle which produces sound out of the range of human hearing. Dogs can hear sounds as high as 45,000 Hz, whereas bats and dolphins can hear up to 110,000 Hz sounds. Other animals have hearing ranges different from that of humans. Humans can normally hear frequencies ranging from approximately 20 to 20,000 Hz. It can give us plenty of information-such as pitch, loudness, and direction. A voice becomes louder when air flow from the lungs increases, making the amplitude of the sound pressure wave greater. A voice changes in pitch when the muscles of the larynx relax or tighten, changing the tension on the vocal chords. This vibration escapes the mouth along with puffs of air as sound. As air travels up and past the vocal cords, it causes them to vibrate. ![]() These folds open and close rhythmically, creating a pressure buildup. People create sounds by pushing air up through their lungs and through elastic folds in the throat called vocal cords. Power is the rate at which energy is transferred by the wave. In general, the intensity of a wave is the power per unit area carried by the wave. Figure 14.10 shows such a cartoon depiction of a bird loudly expressing its opinion.Ī useful quantity for describing the loudness of sounds is called sound intensity. In cartoons showing a screaming person, the cartoonist often shows an open mouth with a vibrating uvula (the hanging tissue at the back of the mouth) to represent a loud sound coming from the throat. But in a traffic jam filled with honking cars, you may have to shout just so the person next to you can hear Figure 14.9.The loudness of a sound is related to how energetically its source is vibrating. In a quiet forest, you can sometimes hear a single leaf fall to the ground. Sound intensity is defined as the sound power per unit area, whereas amplitude is the distance between the resting position and the crest of a wave. ![]() While sound intensity is proportional to amplitude, they are different physical quantities. Students may be confused between amplitude and intensity. |
