"This picture was taken with an Russian film camera, called a Lomo, early in the morning as I waited for the train to go to work downtown. I was passing the time by taking a long-exposure picture of the sunrise over the hills, when the train surprised me and entered the frame. What I didn't realize was that with the shutter already open, the lights of the train were the only things exposed in the shot. So, it made for a 'happy accident' sort of picture -- and one of my best pictures to date."

SAR-QC2 VTOL Aircraft
After going through many changes and cleaning it up. I'll be submitting this SAR-QC2 with USAF as per their solicitation request. Meets and dramatically exceeds requirements. Hydrogen Fuel Cell powered, and utilizing high pressure conforming tank technology I developed.
The underlying tech makes batteries for vtol absolutely obsolete, outright, forever. Also underlying tech results in ACTUAL fuel cell powered electric fixed wing aircraft and commercial aircraft. High pressure conforming tank technology, mixed with fuel cells, and composite aircraft construction. Results in radical advancements in capabilities. Not measured in minutes of endurance, but multiple hours of endurance

Advanced Additive Manufacturing for Hypersonic Aircraft
Utilizing new methods of fabrication and construction, make it possible to use additive manufacturing, dramatically reducing the time and costs of producing hypersonic platforms from missiles, aircraft, and space capable craft. Instead of aircraft being produced in piece, then bolted together; small platforms can be produced as a single unit and large platforms can be produces in large section and mated without bolting. These techniques include using exotic materials and advanced assembly processes, with an end result of streamlining the production costs and time for hypersonic aircraft; reducing months of assembly to weeks. Overall, this process greatly reduced the cost for producing hypersonic platforms. Even to such an extent that a Hellfire missile costs apx $100,000 but by utilizing our technologies, replacing it with a Mach 8-10 hypersonic missile of our physics/engineering and that missile would cost roughly $75,000 each delivered.
Materials used for these manufacturing processes are not disclosed, but overall, provides a foundation for extremely high stresses and thermodynamics, ideal for hypersonic platforms. This specific methodology and materials applications is many decades ahead of all known programs. Even to the extend of normalized space flight and re-entry, without concern of thermodynamic failure.
*Note, most entities that are experimenting with additive manufacturing for hypersonic aircraft, this makes it mainstream and standardized processes, which also applies for mass production.
What would normally be measured in years and perhaps a decade to go from drawing board to test flights, is reduced to singular months and ready for production within a year maximum.
Unified Turbine Based Combined Cycle (U-TBCC)
To date, the closest that NASA and industry have achieved for turbine based aircraft to fly at hypersonic velocities is by mounting a turbine into an aircraft and sharing the inlet with a scramjet or rocket based motor. Reaction Engines Sabre is not able to achieve hypersonic velocities and can only transition into a non air breathing rocket for beyond Mach 4.5
However, utilizing Unified Turbine Based Combine Cycle also known as U-TBCC, the two separate platforms are able to share a common inlet and the dual mode ramjet/scramjet is contained within the engine itself, which allows for a much smaller airframe footprint, thus engingeers are able to then design much higher performance aerial platforms for hypersonic flight, including the ability for constructing true single stage to orbit aircraft by utilizing a modification/version that allows for transition to outside atmosphere propulsion without any other propulsion platforms within the aircraft. By transitioning and developing aircraft to use Unified Turbine Based Combined Cycle, this propulsion system opens up new options to replace that airframe deficit for increased fuel capacity and/or payload.
Enhanced Dynamic Cavitation
Dramatically Increasing the efficiency of fuel air mixture for combustion processes at hypersonic velocities within scramjet propulsion platforms. The aspects of these processes are non disclosable.
Dynamic Scramjet Ignition Processes
For optimal scramjet ignition, a process known as Self Start is sought after, but in many cases if the platform becomes out of attitude, the scramjet will ignite. We have already solved this problem which as a result, a scramjet propulsion system can ignite at lower velocities, high velocities, at optimal attitude or not optimal attitude. It doesn't matter, it will ignite anyways at the proper point for maximum thrust capabilities at hypersonic velocities.
Hydrogen vs Kerosene Fuel Sources
Kerosene is an easy fuel to work with, and most western nations developing scramjet platforms use Kerosene for that fact. However, while kerosene has better thermal properties then Hydrogen, Hydrogen is a far superior fuel source in scramjet propulsion flight, do it having a much higher efficiency capability. Because of this aspect, in conjunction with our developments, it allows for a MUCH increased fuel to air mixture, combustion, thrust; and ability for higher speeds; instead of very low hypersonic velocities in the Mach 5-6 range. Instead, Mach 8-10 range, while we have begun developing hypersonic capabilities to exceed 15 in atmosphere within less then 5 years.
Conforming High Pressure Tank Technology for CNG and H2.
As most know in hypersonics, Hydrogen is a superior fuel source, but due to the storage abilities, can only be stored in cylinders thus much less fuel supply. Not anymore, we developed conforming high pressure storage technology for use in aerospace, automotive sectors, maritime, etc; which means any overall shape required for 8,000+ PSI CNG or Hydrogen. For hypersonic platforms, this means the ability to store a much larger volume of hydrogen vs cylinders.
As an example, X-43 flown by Nasa which flew at Mach 9.97. The fuel source was Hydrogen, which is extremely more volatile and combustible then kerosene (JP-7), via a cylinder in the main body. If it had used our technology, that entire section of the airframe would had been an 8,000 PSI H2 tank, which would had yielded 5-6 times the capacity. While the X-43 flew 11 seconds under power at Mach 9.97, at 6 times the fuel capacity would had yielded apx 66 seconds of fuel under power at Mach 9.97. If it had flew slower, around Mach 6, same principles applied would had yielded apx 500 seconds of fuel supply under power (slower speeds required less energy to maintain).
Enhanced Fuel Mixture During Shock Train Interaction
Normally, fuel injection is conducted at the correct insertion point within the shock train for maximum burn/combustion. Our methodologies differ, since almost half the fuel injection is conducted PRE shock train within the isolator, so at the point of isolator injection the fuel enhances the combustion process, which then requires less fuel injection to reach the same level of thrust capabilities.
Improved Bow Shock Interaction
Smoother interaction at hypersonic velocities and mitigating heat/stresses for beyond Mach 6 thermodynamics, which extraordinarily improves Type 3, 4, and 5 shock interaction.
6,000+ Fahrenheit Thermal Resistance
To date, the maximum thermal resistance was tested at AFRL in the spring of 2018, which resulted in a 3,200F thermal resistance for a short duration. This technology, allows for normalized hypersonic thermal resistance of 3,000-3,500F sustained, and up to 6,500F resistance for short endurance, ie 90 seconds or less. 10-20 minute resistance estimate approximately 4,500F +/- 200F.
*** This technology advancement also applies to Aerospike rocket engines, in which it is common for Aerospike's to exceed 4,500-5,000F temperatures, which results in the melting of the reversed bell housing. That melting no longer ocurrs, providing for stable combustion to ocurr for the entire flight envelope
Scramjet Propulsion Side Wall Cooling
With old technologies, side wall cooling is required for hypersonic flight and scramjet propulsion systems, otherwise the isolator and combustion regions of a scramjet would melt, even using advanced ablatives and ceramics, due to their inability to cope with very high temperatures. Using technology we have developed for very high thermodynamics and high stresses, side wall cooling is no longer required, thus removing that variable from the design process and focusing on improved ignition processes and increasing net thrust values.
Lower Threshold for Hypersonic Ignition
Active and adaptive flight dynamics, resulting in the ability for scramjet ignition at a much lower velocity, ie within ramjet envelope, between Mach 2-4, and seamless transition from supersonic to hypersonic flight, ie supersonic ramjet (scramjet). This active and dynamic aspect, has a wide variety of parameters for many flight dynamics, velocities, and altitudes; which means platforms no longer need to be engineered for specific altitude ranges or preset velocities, but those parameters can then be selected during launch configuration and are able to adapt actively in flight.
Dramatically Improved Maneuvering Capabilities at Hypersonic Velocities
Hypersonic vehicles, like their less technologically advanced brethren, use large actuator and the developers hope those controls surfaces do not disintegrate in flight. In reality, it is like rolling the dice, they may or may not survive, hence another reason why the attempt to keep velocities to Mach 6 or below. We have shrunken down control actuators while almost doubling torque and response capabilities specifically for hypersonic dynamics and extreme stresses involved, which makes it possible for maximum input authority for Mach 10 and beyond.
Paradigm Shift in Control Surface Methodologies, Increasing Control Authority (Internal Mechanical Applications)
To date, most control surfaces for hypersonic missile platforms still use fins, similar to lower speed conventional missiles, and some using ducted fins. This is mostly due to lack of comprehension of hypersonic velocities in their own favor. Instead, the body itself incorporates those control surfaces, greatly enhancing the airframe strength, opening up more space for hardware and fuel capacity; while simultaneously enhancing the platforms maneuvering capabilities.
A scramjet missile can then fly like conventional missile platforms, and not straight and level at high altitudes, losing velocity on it's decent trajectory to target. Another added benefit to this aspect, is the ability to extend range greatly, so if anyone elses hypersonic missile platform were developed for 400 mile range, falling out of the sky due to lack of glide capabilities; our platforms can easily reach 600+ miles, with minimal glide deceleration.
Wigan Cenotaph and War Memorial to the
Fallen of the Great War 1914-18
THE Cenotaph to almost 2000 men - and one
woman - from the former County Borough of
Wigan who fell in the Great War, 1914-18 was
unveiled 75 years ago on Saturday 17 October
1925.
The memorial which was
unveiled that day was the
culmination of six years’ effort
and hard work. As early as
September 1919 Wigan Town
Council had debated the
possibility of erecting a
memorial to the fallen, and in
November 1919 a War Memorial
Committee was established,
chaired by Alderman Ainscough.
This committee met at irregular
intervals to co-ordinate
arrangements. In September
1920 the possibility of replacing
the temporary shrine to the
fallen, which had been
spontaneously built in Mesnes
Park, with a permanent
memorial was put forward to the
Borough Engineer, who
estimated the cost at £1500. In
April 1921 the committee
recommended that the fountain
in Mesnes Park should be
removed and replaced by the
new war memorial; the
Council’s Property, Parks and
Markets Committee, however,
disapproved of the choice of site.
Discussions in committee
concerning a suitable location
continued and several locations
were reviewed:
*various other sites within
Mesnes Park.
*outside the Post Office in
Wallgate.
*at the junction of Wigan
Lane and Swinley Road.
*on the Market Square.
*in the Market Place.
*in the grounds of the Royal
Infirmary.
Fundraising also continued
and in November 1923 a street
collection raised over £2000 - a
tremendous sum in those days. In
1924, with time rapidly passing,
the War Memorial Committee
finally chose an acceptable site -
immediately in front of All Saints
Parish Church, in the very centre
of the town - and the Rector and
Parish Council promptly donated
the land.
Unveiled
Events now moved rapidly
and by February 1925 the full
Town Council accepted the
design by their chosen architect
Sir Giles Gilbert Scott, who had
built Liverpool’s Anglican
Cathedral. By May the sculptor
Edward Owen Griffiths was able
to commence work levelling the
site and creating what is now All
Saints Gardens; construction
advanced so rapidly that it was
finished in time to be unveiled in
October 1925, allowing a
Remembrance Day Service the
following month. The final cost
was £4,000, paid for entirely by
public subscription.
Shortly after noon on
Saturday 17 October 1925 both
Wallgate and Market Place were
thronged with a huge crowd and
traffic was halted all afternoon.
The weather during the morning
had been showery but the rain
ceased shortly after 3 o’clock.
The small square immediately
around the Cenotaph was
restricted to ticket holders, and
owing to the shortage of space it
was only possible to
accommodate one relative for
each of the deceased whose
names were engraved on the
tablets, although a special
enclosure was set aside for the
orphan children.
The Mayor, who had lost a
son in the war, opened the
ceremony with a short speech:
“We are come to honour our
brethren who gave their lives for
us and for this country in a just
cause. This memorial is the
witness of our love for their
memory; and the constant
pledge and reminder to us of
their valour and our duty.”
Mr. J.M. Ainscough, the
main driving force behind the
project, then added:
“We are assembled this
afternoon to fulfil an obligation
which has been far too long
delayed; an obligation to place
in some conspicuous position a
permanent tangible memorial to
those of our townsmen who gave
their lives in the great struggle of
1914-18 that we might have
peace and security. After a long
and anxious deliberation it was
decided to place the memorial on
this site in the very centre and
heart of our town, a crowned
cross the symbol of sacrifice and
victory. On these stones we have
carved the names not of those
who distinguished themselves in
the fight; nor that great number
who, thank God, returned
unscathed many of whom are
with us today, but the names of
our fellow townsmen who went
out in the vigour of strength and
youth never to return. I trust then
that in the future our people will
approach this spot with even
greater reverence than in the
past and that this memorial may
never be defiled by any
sacrilegious hands.”
Military Dignitaries
Among the military
dignitaries present was Colonel
Sir Henry Darlington,
Commanding Officer of the 1/5
Manchesters, Wigan’s territorial
battalion, and Major General
Solly-Flood who had
commanded their division, 42nd
Division. The actual unveiling
was by General Lawrence who
had been brigadier of the 1/5
Manchesters in Gallipoli and had
commanded the 66th Division
including the 2/5 Manchesters.
He spoke briefly:
“I believe that if those whose
names are on this monument
could convey a message to us
today it would be to say:
‘Be of good cheer
The night is passing
The dawn is at hand
Only have faith in
yourselves
Have faith in your country.’
And perhaps what is better still,
when your time comes and you
pass to another life you will meet
these old comrades that have
gone before you and you will be
able to say:
‘We carried on the fight.
We never gave in.’
I unveil this memorial placed here
in the memory of the men of
Wigan who fell in the Great War.”
After the Doxology and
National Anthem the church
bells pealed and there was
wreath-laying, first by officials
and relatives of the fallen then by
the general public. As he laid his
personal wreath the late Private
Thomas Woodcock’s little son
wore his father’s Victoria Cross.
Poignant Reading
How were the names
collected? Already in July 1919
the Borough Library had written
to the local newspapers to ask
families and next-of-kin of the
fallen to submit individual
names and had circularised local
churches and firms with a
request for them to send in lists
of their congregations or
employees killed in action. Their
replies exist in the Borough

An organ grinder on the streets of New York's Lower East Side circa 1910. 5x7 glass negative, George Grantham Bain Collection
The Monkey Is Off Camera
Submitted by namron2u on Tue, 12/11/2007 - 1:06am.
It is a virtual certainty that there was a monkey nearby.
The children appear to be watching something off to the right, possibly the monkey asking for money.
The monkey could also be behind the grinder, the boy to his rear appears to be holding a tether.
Angelo Rulli is an organ grinder historian. He says that while the music was supposed to be the real draw, the organ grinder's monkey was a necessary tool of the trade.
"The monkey was a matter of economics. Because the monkey has an opposable thumb the monkey could hold a cup and by holding a cup, the monkey could go out into the crowd and bang people on the knees and collect money while the grinder was plying his trade."
The monkey may have collected the cash, but it wasn't necessarily for the reason you'd think. It was more often to get rid of them rather than for musical appreciation.
"The irony of the grinder and the music that was played is that as often as not, they were paid to get out of the neighborhood...because it was for the most part terrible music.Ultimately, over the years, all of the major cities in America imposed laws, very, very strictly enforced laws as to the hours that a grinder could be on streets."
In the end though, it wasn't laws or bad music that finished off organ grinders.
"The transistor changed everything, music was now affordable for every American family it wasn't necessary to go to the streets for music. And at about the same time there became a greater awareness of the way that animals were being used for profit. So the organ grinder and the monkey sort of faded away more or less about the same time, after WWII.".

"The fruit fly compound eye under the confocal microscope (immunostained for nucleus and F-actin markers). This particular fly has a mutation in a signaling pathway gene which results in impaired cell-cell communication during eye development. Normally, cells in the developing eye communicate with one another effectively to form a perfect hexagonal lattice, which is important for vision. When this communication is broken, it results in irregularities in the final pattern. This one (in picture) seems almost perfect, except in the middle!"
