STEM education from personal experience - Physics, boomerangs, Michelin tyres and the laws of motion

Friday 6th August 2022 scheduled bike repair from Mike Bike Fix Grampian from Bucksburn Repair, great mobile bike repair specialist visits homes can make bike repairs on the spot from a van available by booking over the phone but for servicing he may take a bike away. Servicing bikes often needed just like how cars need servicing. Mobile bike repairs can be useful but actually standard mountain bikes can be cost effective to buy new outright and second hand bikes can be put up for sale donated also to Rotary groups sometimes for Africa - Halfords repair donated bikes for Africa.

Physics actually part of Engineering and is linked to the laws of motion - throw a boomerang in the garden and it comes back to you. The Boomerang is an Australian concept actually and Boris Johnson did promote the Australian points-style immigration policy during the general election of December 2019.

Forgetting can be a common problem. Forgot to mention to Mum yesterday after visiting downtown Aberdeen and the old under road tunnel from Windmill Brae to Netherkirkgate the left bike brake snaped - the right brake is not that effective actually and bike repair cannot be done on the spot at shops such as the Edinburgh Bicycle Co-operative on George Street due to requirement for specialist parts also buses may not allow bikes to board (foldable bikes might be allowed on buses) but doctors do say exercise is good for everyone, daily exercise is to be encouraged so really walking and cycling during periods of snow in Aberdeenshire may still be necessary without longer winter holidays during periods of harsh weather and use of e-learning for education and digital course materials. Winter weather in Aberdeenshire is usually harsh - last winter 2021-2022 several strong winds and power lines down also snow frequently comes in the North-East of Scotland - those in Aberdeen actually may less likley experience really deep snow and have less struggles than those in Aberdeenshire.

Those who embrace active travel more often will likely live longer, healthier and productive lives - those that suffer with health complaints can actually be jealous. Active modes of travel take longer, be more time-consuming and there is a big underground car park at the big substantial granite AB1 building of the Procurator Fiscal in Aberdeen near Golden Square and Golden Square has EV electric car charges or at least one also bike racks for secure storage on the street, so presumably those who prosecute people are more than likely to use vehicles powered by electric, hydrogen fuel cell technology that emit water vapour and petroleum.

Big issue actually 100 one hundred people may attend Aberdeen Sheriff Court on a single day all given 10am or ten in the morning just after cowboy time - traditionally ten to ten - not separate appointments for flexible travel by bike. Slots and appointments actually for court cases helps people to get there and turn up on time - appointment windows is like the windowing concept in computer networks.

Slots and appointments for court actually translate to use of video for people attending court via video link over the shared medium the Internet - also use of Leyer 2 two Tunnelling Protocol can encrypt connections using a Virtual Private Network. Video link actually has potential for more flexible use of time with also renegotiation - Internet communications use TCP Transmission Control Protocol and a 3-way handshake with an ACK to say thanks Acknowledgement packet for a message received also a SYN bit for synchroisation and syncing connections or establishing a connection.

The SSL renegotiation flaw can affect different types of systems. It is essentially caused by a vulnerability in the client-initiated renegotiation of SSL/TLS for existing server connections. Some of the symptoms of renegotiation issues include: It fails in the case of a virtual server processing SSL connections.

SSL/TLS client-initiated renegotiation is a feature that allows the client to renegotiate new encryption parameters for an SSL/TLS connection within a single TCP connection. During the SSL/TLS handshake the server incurs a higher computational cost.

Starting a new handshake negotiation inside of an existing secure session is called renegotiation.

A sliding window is also known as windowing. A sliding window is a method for controlling sending data packets between two network devices where dependable and sequential delivery of data packets is needed, such as using the Data Link Layer (OSI model) or Transmission Control Protocol (TCP). Data packets usually sent unordered but windowing brings flow control in essence to a computer network.

Buffering linked to the concept of windowing can cause a problem if the sending device transmits data much faster than the receiving device is able to manage it. Windowing in a windowing environment, data is sent in groups of segments that require only one acknowledgment. Groups of messages help to bring more order to chaos over the Internet and in data communications.

Vendettas actually can actually come from people being frustrated by the use of computers and the letters for a court case came from unknown Fiscal deputes no name often mentioned so no accountability (all MSPs usually are known to constituents), yet all names of defendants go on the court role page which is publicly accessible linked to the Scottish Court Service whether innocent or guilty - people maybe more jealous of those who have seemed to have mastered technology but actually the Scottish government did admit that the landscape is dynamic and keeps changing. Mastering technology may come with hurdles and frustrations also other issues as well and changes constantly challenge everyone.

Openness is always better - admitting to crimes being open about your life, open yourself up to scrutiny. Drivers actually can beep their horns in annoyance but actually they are more protected that pedestrians and cyclists - video smart specs and smartphones via video can really capture driver annoyance from behind the wheel, capturing also number plates for review and playback later.

Having restraint when driving is important and actually drivers frequently flash their headlights suggesting it is safe to turn into a side road while traffic continues to travel quite quickly. Graeme Bowen of L and A Driver training advised on flashing headlights for vehicles (UK safest driver from Press and Journal 2004, newspaper archives keeping records is important and provides a tract into history through British Newspaper Archive).

When this person was learning to drive Graeme Bowen advised that flashing lights can be misleading because drivers coming out a side road may interpret a cue it is safe to come out - actually flashing headlights maybe given as a signal between two vechiles travelling in opposite directions. Vehicle headlights frequently flash coming down Westhill Drive in Westhill, Aberdeenshire and vehicles show little evidence of slowing - always taking longer and waiting to turn right and at junctions is safer. Driving examiners actually may add points for too much hesitation - there is a need to really take care when behind the wheel.

Sometimes when drivers flash headlights they do actually slow down - there is another issue with judging speed and children can have more difficulty with this. They may learn the Green Cross Code (think Tufty), drivers need to know the Highway code. Always remember the Tortoise and the Hare race from primary education - the Tertoise and going slower beat the Hare in the end, sometimes going slower may prolong life in a sense be safer at the end of the day.

Issues with headlights certainly justifies speed limit reductions to 20Mph in towns and cities from 2025 - a Scottish government policy decision that has been made originating from the Green Party and Patrick Harvie.

Slowed traffic in an urban environment will make it easier for drivers to give way, pull into the side of the road for emergency services vehicles to enable swift response to life threatening incidents.

The technology industry is highly competitive with competing systems, different platforms, nuances, conflicts, conflicting file formats and the need for file conversion, memory leakages and interrupt requests - interruptions maybe logged in Windows Notepad TXT files (universally supported) and be visible in Event Viewer as events in Windows 10 version ten, also error logs often get produced in both Windows 10 and also computer networks - the Internet Control Message Protocol sends error diagnostic information between routers on the backbone on the Internet.

Advantage in life comes from wealth often and people progressing their careers - legal professionals often wealthy whether prosecuting or defending.

Judges intelligent usually consider bipartisan in cases and absolutely no warrant has been issued to date - this is 3rd third August 2022 and the last scheduled court appearance was the previous Friday 29th July 2022 with previous cases scheduled on 8th July 2022 also 17th June 2022 (supposedly missed but police delivered the notification via letter after this date) and there was an alleged date in May sometime, a delay of five days since last scheduled court appearance and absolutely no warrant issued.

Judges often command respect so surely it would be unreasonable for a warrant to be granted now - multiple judges consider without prejudice and this stipulated in the Criminal Procedure Scotland Act 1995 linked to High court cases and online web-based materials scale up multiple beneficiaries, also objectors amplifying disastisfacation, for information viewing in the online world cutting also repeating, wasted time making online information really useful for purposes linked to education to use staff resources efficiently like in primary and secondary schools. Online web-based materials enables greater scrutiny of all actions actually - also people being willing to admit to what they have done, seen and events witnessed can lead to advancements across multiple industries. Who is viewing this web page anyway?

Failing bicycling brakes necessitate bike maintenance and Michelin tyres enable faster travel - this is not Poetry in Motion, it is linked to sustainable travel

Brakes on bikes actually are not really essential around the Aberdeen area due to need for constant peddling often when people take care peddle slower - also routine rythmic cycling constant peddling in the same gear is much better for the health of cyclists.

When bikes go slower actually stopping is effective easily using feet also grass verges - always being able to get off a bike for downhill stretches makes bikes suitable for longer distance travel.

Physics and motion also linked to Michelin tyres - wheels do speed up travelling and thicker tyres are often more durable with punctures less likely.

Mountain bikes may also be preferred for easier maintenance overall than bikes with thinner tyres such as Hybrid bikes and also road bikes typically racers which maybe more likely used in the Tour de France.

Carrera hybrid bike was gifted to Rotary Westhill for Africa because it kept getting punctures, bought around May 2013 actually since Dad said the mountain bike from childhood was rusted. Actually bike bought from Halfords at the start of 2019, a cheap mountain bike bought for 130 pounds rusted really in no time surprising the next door neighbour former sports journalist who Mum got to tighten brakes.

New mountain bike purchases Specialized best in world make purchased from Edinburgh Bicycle Shop during September 2019. The issue with this bike is the brakes keep snaping actually requiring new brake cables and typically they are a specialised part that require ordering.

Bus drivers need to stick to timetables and schedules - also passengers need to wait around, waste time which can be valuable and cycling opens up possibilities for scenic video capture and shared video can inform others, educate and teach more people open up learning

Really Dad suffering from spinal stenosis issues with the back and legs (nerve signals in the back control the legs) often leaned on a bike to aid walking and also rested stopping to sit down in bus shelters. Buses can actually be infrequent and also bus times are linked to schedules, waiting around and to be a bus driver actually is a stressful job because drivers have to keep to timetables.

STEM Science Technology Engineering and Maths is rising in importance and the basis for maths comes from US President Abraham Garfield who founded Pythagorus. Around the time of Abriham Garfield, there was Chester Arthur the 21st President of the United States of America. Information discovered on Abraham Garfield after looking into the first ladies linked to former US Presidents on Wikipedia - actually the most interesting first lady is Hillary Clinton and she got into trouble for using a private mail server when working as the US equivalent of Foreign secretary which is Secretary of State.

Hillary Clinton wife of former US Prisident Bill Clinton faught the 2008 election run-up bitterly with Barack Obama and opposed Donald Trump at the US election during 2016. From Bill Clinton's time as President, there was really three people - Bill, Hillary and Monica. John Major had a wife and also Edwina Currie. Leading ladies were really important during the mid-1990s. Tony Blair first serving Prime Minister to father a baby in Office - son Leo was born to Cherie Booth QC. Leo was conceived in Tuscany, the area of Italy with Piza also Florence, Livorno and old historic walled town Lucca, this story from the local media the Press and Journal was publsihed during 1999 - newspaper archives always worth paying attention to. Aberdeen's RGU actually been running TechFest for 25 years almost since it was founded in 1992 - it has a big computing, engineering and midwifery departments respecting life also new life.

Bus drivers need to stick to timetables and schedules - also passengers need to wait around, waste time which can be valuable and cycling opens up possibilities for scenic video capture and shared video can inform others, educate and teach more people open up learning. Video represents convergence of audio sound and video and broadens learning alternatives to the deaf hard of hearing and visually impaired communities. Multiple technologies involved in convergence over the Internet for TCP/IP data communications - convegence term from Cisco System originally, the maker of Cisco router equipment, which powers the backbone of the Internet. Cisco very visionary leader in technology circles trained virtually all network engineers and administrators including most industry leaders also employees also engineers of telecoms giant British Telecommunications.

Facebook shared videos from Rubislaw area including Springfield Road around Rubislaw Park Care Home

3rd August 2022 Near the Hazlehead roundabout long grass little rainfall, grass grows more during Summer requires cutting this is environmental services. Grass cutters nearby actually with hoes basic instrument doing weeding also one grass trimmer at Hazlehead Park entrance off the roundabout. Changing climate patterns may mean warmer days. Scotland's climate is temperate but typically those who walk and cycle need more fluid also they may sweat more - cycling more rigorous activity. Big issue around secure bike storage being inadequate at convenience stores but there are railings at the shop by Hazlhead Primary also at the Sainsbury's Local near the railway station.

3rd August 2022 green environmental services happening at the Hazlehead roundabout in Aberdeen near Kingsgate road and by Hazlehead Park road hoe and trimmer the tools being used also van blocks pavement likely to answer mobile phone on the opposite side of the road. Worth mentioning because actually Aberdeenshire Council workmen previously said for health and safety reasons workmen must be near tools to perform outdoor jobs when cutting back hedgerows for example. Van driver just parked up randomly during an active already current video shooting session highlighting how environmental services are happening at the present time, recording an important event given that more environmental operations maybe needed after the following winter. Digital records and visual records can hold Governments to account in future and Councils assisting ability to look back in time - reflect and review. The person that shoots and shares the video may not be the same person who references video - other people may reference a shared video to highlight something and shared video shows what someone else has witnessed. Some great natural phenomena can be seen think the green lights the Northern Lights or Aurora Burealis.

3rd August 2022 a beastie on a colourful plant in Aberdeen Rubislaw area - this video the stuff of Sir David Attenburgh who produced a video about tropical paradise birds and parrots on the BBC, actually witnessing bees pollinating plants and beasties is not that common, but when it happens video does preserve the fleeting moment.

3rd August 2022 Johnston Gardens ducklings swim - brown feathered duck splashes and plays with tail feathers and some ducks swim really close to the camera. Children say feed ducks cut seedless grapes, cooked rice, bird seed, peas, corn and oats not bread to fatten them. In Aberdeen, it is the children that are the leading environmentalists well so says the colourful child-like sign at Johnston Gardens. The children say feeding ducks bread will send the ducks to the doctor - actually is VETs for animals but no such VET will want to see a duck. Actually this is scarcasm from the children.

3rd August 2022 Springfield Avenue and most significant issue with this video is the elderly pensioner actually on Springfield road putting out his brown big garden rubbish also food shared bin. Older people can struggle to put out their waste bins important to recognise it, younger neighbours should helps and also the petrol station opposite is the one that closed and it had a shop and petrol pumps was a grocery store for homes nearby also just further along the Treetops hotel closed. This is an upmarket area of Aberdeen being neglected of services.

3rd August 2022 Video starts off actually at Rose Park Care Home Rubislaw behind wall but seem to miss the care home turned the wrong way missed the entrance when in full flow moving along shooting video - care home near Springfield Road off Rubislaw Park Crescent but Springfield Road explored well to do affluent area of Aberdeen with large houses. Just from assessing the care home from the outside actually when a visitor was leaving (separate video), the care home residents are well cared for, there is a courtyard in the middle not visible from the road wher residents mill about chat having cups of tea and drinks - elderly residents so exercises are nothing strenuous. Really care home residents missing out on the action at nearby Johnston Gardens.

Woodend Craigiebuckler Berryden Northfield this is the Service 11A from Springfield road around Rosepark Care home bus route about 14 times a day Monday to Friday starting from 622am and almost every hour around the same time. The service 15A from Airyhall to Union Square shopping centre does not run on Saturday and Sunday. Off work on the weekend, no shopping in the City Centre for you at weekends by shared public transport. Hop aboard the service 11A instead and go to Berryden retail park at the weekends for either boxed heavy items from Argos or pickup a laptop computer from electrical retailer Currys alternatively do a shop at Sainsbury's the supermarket at Berryden now the Springfield Road petrol station and shop closed. Young people on bikes shown and with bikes no need to wait around - perhaps an electric bike might be a wise choice, bikes often more practical than scooters.

3rd August 2022 This is a private dwelling shrouded in trees - it is not the neighbouring care home - on the ground you could use online maps but actually they may not be the clearest when not using a magnified display and also there is no direction arrow typically showing which way you are facing big issue, a problem shared is a problem halved a weight off.
