![]() ![]() It is also referred to as a constructive plate boundary, as new material is being produced at the boundary surface. This type of boundary is called a divergent boundary. However, ridge push is also presented in recent research to be a force that drives the movement of plates. Research has shown that the major driving force for most plate movement is slab pull, because the plates with more of their edges being subducted are the faster-moving ones. slab pull: older, colder plates sink at subduction zones because, as they cool, they become more dense than the underlying mantle and the cooler, sinking plate pulls the rest of the warmer plate along behind it.ridge push (buoyant upwelling mantle at mid-ocean ridges): newly formed plates at oceanic ridges are warm, so they have a higher elevation at the oceanic ridge than the colder, more dense plate material further away gravity causes the higher plate at the ridge to push away the lithosphere that lies further from the ridge.mantle convection currents: warm mantle currents drive and carry plates of lithosphere along a like a conveyor belt.Three of the forces that have been proposed as the main drivers of tectonic plate movement are: There are a number of competing theories that attempt to explain what drives the movement of tectonic plates. The asthenosphere behaves like a fluid over very long time scales. What drives the movement of tectonic plates?īelow the tectonic plates lies the Earth’s asthenosphere. Observations show that most earthquakes are associated with tectonic plate boundaries and the theory of plate tectonics can be used to provide a simplified explanation of the global distribution of earthquakes, while some of the characteristics of earthquakes can be explained by using a simple elastic rebound theory. Tectonic plates move very slowly relative to each other, typically a few centimetres per year, but this still causes a huge amount of deformation at the plate boundaries, which in turn results in earthquakes. These slabs form the lithosphere, which is comprised of the crust (continental and oceanic) and the upper part of the mantle. The Earth’s outermost layer is fragmented into about 15 major slabs called tectonic plates. We also know that the outer part of the core is liquid, because S-waves do not pass through it. The core is composed of iron and we know that it exists because it refracts seismic waves creating a ‘shadow zone’ at distances between 103º and 143º.

The presence of thermal springs in the Argentera area indicates that the pore fluid is water. A calculation based on a pore fluid factor-differential stress failure mode diagram shows that the required excess pressure is comprised between 7 and 26 MPa. A 2-D analysis with a static coefficient of friction of 0.4 (consistent with the presence of phyllosilicate-rich gouges at depth) shows that the N130☎ fault is unfavourably oriented and that its reactivation is possible only with pore fluid pressure excess in the hypocentral region (6-7 km below surface). Inversion shows that the axis of the maximum principal stress σ1 is oriented nearly horizontal and at 63° from the fault plane and that the intermediate principal stress σ2 is almost parallel to the fault plane. The regional stress tensor in the vicinity of the fault is determined by inversion of focal mechanisms of the 38 events with largest magnitudes of the 2003-2004 swarm. Its reactivation is examined by a 2-D frictional fault analysis. A crustal-scale N130☎ strike-slip fault in the Ubaye-Argentera area, southwestern French-Italian Alps, was the locus of a seismic swarm in 2003-2004. ![]()

![]() The cap of a Platypus pen has an outer layer made with shiny, colourful filament and has an interesting surface pattern and the plastic. The strength of the sandwich is much, much higher than the strength of the two printed layers. Furthermore any weakness is especially problematical when the object is printed with a single wall, as are most parts of a Platypus pen! What to do? Well, the solution to this problem is conceptually easy: make an epoxy-bonded sandwich of nested components. ![]() That inter-layer weakness is not much of a problem for thick-walled objects and for solid objects, but for a long thin-walled thing like a fountain pen it can be critical. The plastic is strong in the direction of its layer plane because it consists of a continuous strand of extruded plastic, but the object can be weak at the layer junctions because the plastic of adjacent layers is incompletely welded together. The layer by layer nature of 3D printing usually leads to uneven strength. You may need a magnifying glass to see it because the part was printed with a high quality printer fitted with a direct drive extruder and the printing settings are optimised to minimise the seam. It does have a seam at the thread that connects to the pen body. There is one component in the Platypus pens that is printed in the conventional layer after layer mode: the section inner. Single wall helical printing is often called ‘vase mode’ printing, and it eliminates seams and pimples by removing the need for filament retractions and un-retractions. Well, not exactly one layer, but the extrusion path is a single helix. Most of the components are printed in a single layer and so there is no seam or pimples. Platypus pens are designed to almost entirely eliminate this problem. The retractions and un-retractions almost always leave visible defects on the surface of the object, defects that are called seams where they are vertically aligned and pimples where they are randomly scattered over the surface. That problem is typically combatted by having the filament retract suddenly just before the layer change and then un-retract when the nozzle reaches the start of the next layer. Each will be dealt with in turn below.Ĭloseup of an FDM 3D-printed object showing clear layer lines and defects that arise during the transition between layers. The layer by layer process of FDM 3D printing brings some important limitations to the objects that can be printed, and those limitations are relevant to fountain pen production. Limitations of FDM printing for pen production It may not need to be said, but Platypus pens are the product of rapid prototyping and iterative design. My second 3D printer-the one on which I print the Platypus pens-is constructed with parts printed by my first, and the first was repaired and improved with new parts printed by the second: a nice RepRap circle. The first RepRap machine was able to print many of the components of itself, which were then used to make a second RepRap machine which printed the parts for a third, and so on. The “Rep” part of RepRap is short for self-replicating. The 3D printers that sparked the development of consumer-level 3D printers were called RepRap in recognition of that role: the “Rap” part is short for rapid prototyping. It’s the total turnaround time from design to inspection and testing that is rapid with a 3D printer, and that short turnaround facilitates design iteration and optimisation prior to the product being manufactured by more conventional methods. A 3D print might takes hours to complete which stands in contrast to a few seconds to injection mould an object from plastic, but the 3D printer is ‘rapid’ because the tooling for the injection moulding process might take weeks or months to make or procure. (And then more time is taken to assemble and finish the pen, but that is not the topic of this blog post.) Rapid prototyping and developmentĭespite their slowness 3D printers are widely used in the process called ‘rapid prototyping and design’. The components for one Patypus fountain pen take about four hours to print altogether. ![]() The layer by layer process intrinsic to 3D printers allows for a remarkable range of object shapes and designs to be formed, but that flexibility comes with a downside: 3D printers are quite slow. If you are interested in learning more about 3D printing then you can read some of my other blog posts, and I recommend the video series about the basics of 3D printing created by YouTuber Tom Sanladerer. ![]() ![]() ![]() Absence during Important Moments: “The day you couldn’t come to my birthday party” – The speaker reflects on significant events where the friend was absent, subtly pointing out the negative influence or distraction of the partner. ![]() This suggests that the partner isn’t being real or honest, and might be pretending to be someone he’s not.

It’s a story of someone watching a close friend in a seemingly toxic relationship, wanting to help and yearning for their attention. NewJeans’ unique lyrical style gives listeners the sensation of conversing with a close friend, inviting them into an intimate circle of trust and emotional transparency.ĭrawing from the theme of “Estimated Time of Arrival,” the track masterfully weaves a narrative about the anticipation and impatience that come with love and relationships. The song vividly captures the feelings and frustrations of youthful relationships, echoing sentiments that resonate with many teenagers. “ETA” by NewJeans is a piece that blends the rhythmic intensity of Break Beat with the laid-back mellowness that the group is known for, punctuated by the energy of Favela Funk. So, in short, this song can be a lesson about being careful with rumors or a touching story about love, depending on how you experience it. It talks about the ups and downs in relationships, the feelings of waiting, and the challenges friends face. But if you just listen to the song’s words and music, it feels like a story about young love. It’s like a warning about believing everything you hear. If you watch the music video, the song talks about how easy it is for people to believe rumors and make quick decisions without knowing the full story.

In 1971, astronomers determined that the X-rays were coming from a bright blue star orbiting a strange dark object. Astronomers saw the first signs of the black hole in 1964 when a sounding rocket detected celestial sources of X-rays according to NASA. The first black hole ever discovered was Cygnus X-1, located within the Milky Way in the constellation of Cygnus, the Swan. ![]() After decades of black holes being known only as theoretical objects. The term "black hole" was coined many years later in 1967 by American astronomer John Wheeler. ![]() First black hole discoveredĪlbert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. It is believed that the interior of black holes could contain a wormhole, the puncture is spacetime, that could offer a portal to another point in spacetime potentially even in a different universe. Wormholes can be thought of as tunnels that connect two separate points in space and time. Over very long timescales, we are speaking about timescales that are much much longer than the age of our universe, the theory states that this trickle of escaping particles will cause the black hole to slowly evaporate. Instead of the particle antiparticle pair existing for a moment and then annihilating each other, one of them can get by gravity and fall into the black hole, while the other particle can fly off into space. When this process occurs near the event horizon of a black hole, strange things can happen. However, they can also recombine and disappear again. When this happens, a particle and its companion anti-particle appear. Quantum theory suggests that there exist virtual particles popping in and out of existence all the time. ![]() Hawking predicted that black holes could also radiate away energy and shrink very slowly. Do black holes die?īlack holes do not die per se, but they are theoretically predicted to eventually slowly evaporate over extremely long time scales.īlack holes grow by the accretion of matter nearby that is pulled in by their immense gravity. The first detected black hole was Cygnus-X1. Over time, as other end products of stellar death were detected, namely, neutron stars seen as pulsars it became clear that black holes were real and ought to exist. It was unclear at the time if these corresponded to real objects in the universe. The black hole solution was found was by Karl Schwarzschild in 1915, and these regions - black holes - were found to distort space extremally and generate a puncture in the fabric of spacetime. The theory of general relativity connects the geometry or shape of shape to the detailed distribution of matter. Einstein's equations describe the shape of space around matter. Who discovered black holes?īlack holes were predicted as an exact mathematical solution to Einstein's equations. This channel circumvents the formation of the traditional star, and is believed to operate in the early universe and produce more massive black hole seeds. Another way that black holes form is from the direct collapse of gas, a process that is expected to result in more massive black holes with a mass ranging from 1000 times the mass of the sun up to even 100,000 times the mass of the sun. ![]() Not all stars leave behind black holes, stars with lower birth masses leave behind a neutron star or a white dwarf. The resulting black hole that is left behind is referred to as a stellar mass black hole and its mass is of the order of a few times the mass of the sun. Stars whose birth masses are above roughly 8 to 10 times mass of our sun, when they exhaust all their fuel - their hydrogen - they explode and die leaving behind a very compact dense object, a black hole. According to the first pathway, they are stellar corpses, so they form when massive stars die. How do black holes form?īlack holes are expected to form via two distinct channels.
