It's a reasonable question, I think. These are jumbucks: This is a tucker bag (carried in front): This seems a problem, in terms of fit. I feel there are limited possible explanations for the jolly swagman's achievement of jumbuck insertion. 1. 19th century sheep in Australia were miniaturized, in an amazing secret leap forward of GM technology. 2. Tucker bags were capable of massive elastic stretching. 3. Lyricist Banjo Paterson reported falsified data when he wrote the line, And he sang as he shoved that jumbuck in his tucker bag Are there other possible means of jumbuck insertion and containment that have …

A Korean robotics engineer has been crushed to death by a robot at a food packaging plant in South Korea while checking out reports of a malfunctioning sensor system. https://www.bbc.co.uk/news/world-asia-67354709 Acoording to the South Korean news agency Yonhap 연합뉴스, the robot which mistook him for a box of vegetables grabbed him, and then pushed his body against a conveyor belt, crushing his face and chest. The robot which had been newly installed in a pepper sorting plant in the Donggoseong Export Agricultural Complex in South Gyeongsang province was designed to lift boxes of peppers onto pallets. An initial test run scheduled for 6 November had been del…

Persistent rumours that the PLAN (Peoples Liberation Army Navy) of Communist China had a nuclear submarine disaster in late August of this year have reappeared recently with new details. https://www.youtube.com/watch?v=3X2BjWnq9R8 According to this update, a CCP type 093 nuclear submarine #417 became trapped in one of the Chinese navy’s own anti-submarine underwater boom defense systems in the Yellow Sea, near the mainland Chinese coastal city of Shantou, to the southwest of Taiwan. According to a Twitter/X post by @Luoxiangzy on 19th October, the incident occurred at 8.30 a.m. on Monday August 21. The submarine #417 had sailed from Qingdao naval base and w…

In existing VR systems, the disconnect between visual cues and vestibular sensations impacts a person's sense of balance and spatial orientation: What you see and experience visually might not align with what your inner ear and body feel. For example, you may be visually moving in one direction while your body remains stationary. This disconnect between visual and vestibular cues can lead to sensations of dizziness, disorientation, and imbalance. what modifications or design considerations(general/specific) can be implemented(to headset or environment) to minimize or alleviate the sensations of dizziness, disorientation, and imbalance that may arise from this mismatch? …

Since at least WW2, scientists and science fans have been speculating about how to accelerate a spaceship fast enough to reach other star systems. The most sought-after method seems to be nuclear fusion (I think,) currently out of reach. But what’s wrong with nuclear fission? If the power of the Hiroshima bomb could be channelled, I would imagine that would get us to alpha centauri pretty damn swiftly. I did hear once that governments will not allow the use of nuclear for space exploration. Anyone know if this is true? Cheerz GIAN🙂xx PS As you've probably guessed I'm not a scientist but I hope to be one day

Hello all, I hope I have the correct category. Affinity installed a Itron Everblue Cyble water meter in my front garden. I can't find any figures. Can I read it myself or do I have to rely on the smart readings please? I like to check my bills Enclosed is a terrible picture, it's a long way down. Greetings

hello using invisibility cloaks i would like to ask how to generate wormholes from wifi, sdr, and 5g wireless. thanks very much.

What is the most cost-effective way to cool a home? We live in very hot climate in this Socal valley. We had many days over 100 F and days over 110 F. We have 2 large evaporative coolers, many electric fans, and central A/C. We are able to stay cool on the hottest days using just our 2 evaporative coolers and maybe a couple of hours of A/C on the hottest days. It seems we are saving energy by not using A/C all day, but rather using most evaporative coolers? Should energy companies be encouraging customers to use evaporative coolers?

Asking here as it seems more of an engineering question Looking at the recent spaceX launch, (ok it failed) there seems to be a move to build bigger and bigger rockets to take us in to space. How much is this really needed? Would we be better off expanding the ISS (or I think the plan is to build a new space station) which can act as a launchpad to take us to the moon, this could be equipped with what could be mini shuttle craft (like on star trek) that can dock and un dock as needed. On earth we can already do vertical take off and landing with aircraft, so these shuttle craft would also be capable of this. We currently have the smaller but reliabl…

n 2022 the BBC filmed inside the OceanGate Titanic submersible that has now gone missing during a dive to see the wreck of the Titanic, which lies on the seafloor about 12,500 feet below the surface, and around 370 miles off the coast of Newfoundland. https://www.bbc.co.uk/news/av/world-us-canada-65958697 In the screenshot below, Stockton Rush the Chief Executive of OceanGate who is believed to be one of five people missing aboard the submersible is seen explaining how it works “It’s got one button, and that’s it. We run the sub with this game controller - It’s made by Logitec, but it’s basically a Sony PS style controller” he says - What could possi…

Hi all, my questions are as follows... When going to college is it possible to get a mathematical Engineering degree with an emphasis in computer science and computer engineering as well as mechanical engineering? I need a degree that will cover these four fields reasonably or is mathematical engineering enough? Also, will have to get multiple Degrees?

A report by NATS (National Air Traffic Services) says that a catastrophic failure of the UK air traffic control system on the August 28 Bank Holiday this year was a caused by a “one in 15 million’ software failure event. https://publicapps.caa.co.uk/docs/33/NERL%20Major%20Incident%20Investigation%20Preliminary%20Report.pdf According to this report, a key sub-system called FPRSA-R (Flight Plan Reception Suite Automated) was thrown into a fail-safe shutdown mode when it attempted to process a flight plan submitted by an un-named airline which included two identically named (but geographically distinct) waypoint markers. The back-up system which runs the same softw…

Hi. Surplus energy from solar panels has been heating water during the day in a non-sealed 200 litre (55 gallon) drum and used in winter as heating source during nightime. What materials could store more energy instead of water, that along weeks diminishes level from steamy evaporation ? Oils have a lower temperature coheficient but can be heated well to >200C; perhaps yielding a greater Q = mCΔT If heating from electric elements in a oil container has lots of iron, or aluminium junk submerged, would it keep more heat ? What simple common materials as rocks, glass?, polyethilene, metal junk in oil bath (or something else) -with no phase change com…

Good day. Sound waves as speech make a dynamic microphone diaphragm vibrate. The waves hitting the ‘exposed’ side of the diaphragm make it to vibrate because has a minimal mass. If the diaphragm was massive, it would not perform well as a microphone. The back side of the diaphragm can be exposed to the same vibrations as the front, or be encapsulated shielded from being exposed to the vibrations. If the back side is not shielded, the motion of the diaphragm can have cancellation as vibrations push simultaneously in-phase to both sides yielding little or no movement. If the rear of the diaphragm is enclosed and not exposed to the front-hitting vibration…

Hello I'm trying to make a motorized rollerskate. if you've seen the show Air Gear, then, you know what i'm trying to make i don't know if their is some sort out in the market today but i would like to own a pair. or make a pair. doesn't matter. if anyone could help with this i would greatly apriciate it.

How do boosted fission bombs have fusion fuel in centre since that is where the initiator is?

Hi all, I had posted this originally in the homework help section, but the assignment is completed and submitted, so no longer relevant. I thought some might find it interesting. The crux of the article revolves around a hypothetical 5,000 metric ton (dry mass) spacecraft, and examines propellant requirements vs exhaust velocity, the power requirements to achieve the requisite amount of thrust for an interstellar journey in one lifetime, the technology requirements to achieve that power output, and the thermal control system that would be required for any resultant waste heat. Article is aimed at the "average" reader interested in the topic, so I aimed to …

This youtube video is a real eye-opener. After watching it, you won't be anywhere near as confident in your bike or shed lock. It's made me determined to pay a lot more next time I buy a lock. Has anyone got any methods that they consider failsafe?

Director Christopher Nolan shot his new biopic ‘Oppenheimer’ (2023) in 70mm Imax format, and the new film has been given a rare theatrical release in that format (the first since ‘Tenet’ in 2020). The Imax format film roll for this new 3 hour film is about 11 miles long, and weighs some 600lbs. The Imax engineers not only had to design a new enlarged platter system to carry this amount of film: they have also issued a software emulator for the long defunct PalmPilot m130 hand-held PDA - because back in the day in 2002 this was the platform for the custom PDA app most often used by Imax projectionists as their ideal tool to control the long-play Imax Quick Turn Reel …

How is stainless steel product normally polished? On Google, I find that there are a lot of different answers. What is the most common way for the industry to polish stainless steel product? Is there any special machine for getting the job done? Normally what are the price ranges for those machines?

How do external neutron initiators work in boosted fission bombs? Where are they placed to initiate fission reactions? Are they sent through tube and how?

Hi all, I am a biochemistry premed undergraduate entering my third year in the fall. Presently, I study at the Division of Nephrology at Vanderbilt University Medical Center where I have interned for the summer (hence, inspiration for the name "HEK-293-DDR1b"; we study kidney fibrosis!😉) Anyway, I write to address my concerns about undergraduate collaboration in science across institutions amongst other students and faculty. My undergraduate studies are at a small liberal arts college. Though, nonetheless, I have been able to write two successfully funded grant proposals within the field of wood-based translational materials science. While the lab resources are …
