a weblog of whereabouts & interests, since 2010
It’s Friday night in Tokyo and I am at the airport.
I had time today to squeeze in one more train ride, on the Yurikamome Line.
The train on this line runs on an elevated, fully automated track (so no driver) that connects Shimbashi Station to Toyosu Station via the popular Odaiba area.
On Wednesday night I did my mandatory (mandatory for me) walk-about along the main street in Ginza, Tokyo’s luxury shopping district. The street is named Chuo-dori, which translates to ‘Central Street’.
The sign in the first picture says ‘Ginza Block 6’.
Stores on Chuo-dori close at 7 or at 8. The Onitsuka Tiger store (Japanese footwear maker) was filled with sneaker aficionados right until closing time. Look for the storefront with the cool tiger neon sign in the pictures below.
I was out of the bed in my hotel in Seoul shortly after 4 am this morning.
I had to take the first train of the day (5.28 am) on Line 1, from City Hall Station to Seoul Station.
At Seoul Station, I took the 6 am Airport Express train into Incheon International Airport.
(Cost: US$9, with a free bottle of mineral water from Jeju Island thrown in. For me, it’s not really about the cost, though. I just think taking the train is a lot more interesting than taking a taxi.)
The flight out to Tokyo’s far-away Narita Airport was slightly delayed, but went without incident.
I could not very well go up Seoul Tower, and leave Lotto World Tower out, right?
So off I went today to Lotto World Tower, even though it was a 40 minute train ride out there.
There is an express double-car elevator that whisks the humans inside up to the 117th floor* in one minute flat. I felt a little vertigo, and my ears popped on the way up. There no view to the outside, just display screens on the sides and ceiling of the car.
*The Seoul Sky observation deck in the Lotte World Tower spans seven floors, from floors 117 to 123.
As it happens, both the departure and arrival airports for my flight today are located on man-made islands.
It took two train rides to get me to Osaka’s Kansai International airport (KIX), and after I had arrived at Seoul’s Incheon airport (ICN), two more trains to get me to my hotel in the city.
I set out this morning to take a ride on the streetcar that starts at Tennojiekimae Station. Just with dumb luck, I discovered upon arriving there that Osaka’s tallest building is right there, as well.
So I first went up to the observation deck on the 60th story of Abeno Harukas, and then took a short ride on the street car.
Today was my last full day in Osaka.
I am flying out to Seoul, Korea (two hours on Asiana Airlines), in the morning.
I walked over to the West Gate today (both days I had entered at the East Gate), where I found Astro Boy.
I also tracked down the Japan Pavilion with its beautiful ‘golden hat’ design. The Golden Surface of the Japan Pavilion was created by the designers Nikken Sekkei. They used an iridescent color shining technology— a technique that involves engraving microgrooves onto the surface, which interact with light to produce a dynamic, multi-colored sheen that changes with the viewing angle.
As the sun was setting, everyone went up to the Grand Ring, to watch the daylight end.
I made it to Expo 2025 Osaka!
It’s hot and it’s crowded with very, very long lines at most pavilions— the ones that allow you in without a reservation, that is.
Entrance to the top-rated pavilions are pre-allocated by a lottery system. I struck out despite diligently applying, as far out as three months before my visit today.
No matter, once you have made it into the entrance gate (with 180,000 others), you are in a world onto its own, inside the Grand Ring. The Ring is the world’s largest wooden structure, constructed on Yumeshima (夢洲), the artificial island located in Osaka Bay.
The USA pavilion is a structure designed by Trahan Architects with two triangular wings and a raised translucent cube flanking a central plaza. It features video imagery that features the Plains, the mountains and the cities in the US— and hey! Seattle’s Pike Place market made an appearance as well.
I was mesmerized by the installation of shiny cubes called null². The sun bounced off the surfaces, and a low sound was emitted from the structure.
Developed by Yoichi Ochiai, the pavilion’s structure is based on a cubic grid of voxels measuring 2 to 8 m (6 ft to 26 ft) wide. The facade is covered with a membrane that resembles a mirror. [Source: Wikipedia]
Look for a few images (towards the end) beamed out from the enormous high-resolution screen outside the Korea pavilion. The three-story pavilion has a high-resolution screen on its facade that is 27 m (89 ft) wide. The screen displays on a spectacular series of animated images and videos.
South Africa withdrew from Expo 2025 Osaka in late 2024 despite repeated invitations from the Japanese government, citing the country’s ‘financial constraints’.
All went well with my train ride to Osaka.
It is an amazing experience to travel at 175 mph (280 km/h) on the tracks, with the landscape flying by the window.
Yokohama is south of Tokyo, and one of the first Japanese ports that opened to foreign trade, in 1859.
I made a run there on Saturday morning on the Nozomi shinkansen out of Shinagawa station— a trial run of sorts, for my trip to Osaka on Sunday.
It’s 19 km (12 miles) and only 18 minutes from station to station. A trip by car would take about 40 minutes.
There was drizzle on and off here in Tokyo on Thursday, at a damp 85°F (30 °C).
Outside, I could only take pictures here and there with my big camera, but managed to get a few of the iconic 1914 Tokyo Station building (extensively renovated and restored in 2012).
I also made my first run to the Yodobashi Akiba store in Akihabara.
It’s been 50 years since the launch of Viking I, the first US spacecraft ever to land successfully on Mars.
Research from recent years suggests that the lander touched down where a Martian megatsunami deposited materials 3.4 billion years ago.
(The remains of the original Viking 1 lander are on the surface of Mars, where it had landed on July 20, 1976. It was a stationary lander and did not roam around. It did have an orbiter with solar panels that completed 1,485 orbits around Mars. While it no longer transmits data, the orbiter continues to orbit the planet! )
Construction of the Viking 1 spacecraft was done primarily by the private company Martin Marietta (now Lockheed Martin). The team worked for six years to build the ground-breaking spacecraft. The cost came to roughly $1 billion— about $6 billion in today’s dollars.

1. The Historic Liftoff
The countdown ended in a roar of fire and smoke as Viking 1 lifted off from Cape Canaveral on August 20, 1975. The Titan IIIE-Centaur rocket carried both an orbiter and a lander, marking NASA’s boldest step toward exploring Mars.
2. The Long Cruise to Mars
Viking 1 traveled nearly 11 months through space before arriving at Mars. This interplanetary cruiseinvolved careful navigation to ensure the spacecraft reached its target orbit with pinpoint accuracy.
3. Mars Orbit Arrival
On June 19, 1976, Viking 1’s orbiter fired its engine to settle into orbit around Mars. From this vantage point, it began photographing the surface to find a safe and scientifically valuable landing site.
4. The First Soft Landing on Mars
On July 20, 1976, exactly seven years after Apollo 11’s Moon landing, Viking 1’s lander touched down in Chryse Planitia, becoming the first fully successful Mars lander in history.
5. Stunning Panoramas of a New World
Viking 1 sent back the first high-resolution panoramic photos of Mars, revealing a rocky, rust-colored landscape beneath a salmon-pink sky, images that captured the imagination of people worldwide.
6. Searching for Life
Equipped with biology experiments, Viking 1 attempted to detect signs of life in Martian soil. The results were puzzling: some tests gave unexpected positive readings, but most indicated no organics, sparking debates that continue to this day.
7. Mapping Mars from Above
The orbiter mapped vast swaths of the planet, from giant volcanoes like Olympus Mons to canyons deeper than Earth’s Grand Canyon. These images shaped our understanding of Martian geology.
8. Years of Operation
Viking 1’s lander operated for over six Earth years (2,245 Martian sols) making it the longest-running Mars surface mission until 2010, when NASA’s Opportunity rover broke the record.
9. A Sudden Goodbye
In November 1982, a faulty command ended communications with the lander. The orbiter had already completed its mission, but Viking 1’s contributions to science remained secure.
10. Inspiring Future Mars Missions
From Pathfinder to Perseverance, every Mars mission since Viking 1 has built on its legacy. It proved we could land safely, operate for years, and study Mars in depth.
I take my new camera with me now, every time I go for a walk.
I’m still learning to adjust the exposure and the auto-focus mode.
I also paired the camera with my iPhone (via Bluetooth) so that that the GPS coordinates of my location for each picture can be recorded in the camera on the metadata for the image.
There is a drawback, though: the camera’s battery runs down much more rapidly if it is connected to the phone all the time.
The camera actually has an airplane mode, but it’s a pain to switch it on and off multiple times while walking around.
Better to carry one or two spare batteries to pop into it when one runs out.
I have a new camera, after eight years: a Sony α7CR.
It is a mirrorless, full-frame digital camera that takes 61-megapixel pictures— so it is able to capture stunning detail.
I took at few pictures today (at about 6 p.m. tonight) of the fast ferries from Kitsap Transit at Pier 50 on the Seattle waterfront.
The fast ferries are passenger-only, so no vehicles.
The first pictures shows the Enetai at the terminal, waiting to depart for Southworth on the Kitsap Peninsula.
The Solano is approaching in the distance, about to complete its 26-minute crossing.
The Enetai backs away and departs after the Solano has docked next to it at the terminal.
Another fast ferry arrived shortly after that— the Reliance— in from Bremerton.
Survivors of the atomic bombing have campaigned for a world free of nuclear weapons. But 80 years on, that dream is fading. Three of Japan’s neighbors — Russia, China and North Korea — are nuclear powers, and Tokyo depends on the American nuclear umbrella to protect it. With tensions in the Pacific heightening and firsthand memories of nuclear devastation waning, more Japanese are questioning the national commitment to peace at all costs.
– Hannah beech reporting for the New York Times from Hiroshima
Sadly, it seems unlikely we will ever have a planet without nuclear weapons.
The world also stopped building nuclear reactors after some major accidents turned public support against it. Now we need them for fossil-free energy generation, and for all those power-hungry AI server farms.
By the way, I thought— how is that first fusion reactor coming along?
Google AI Overview says:
While the dream of practical fusion energy has been “30 years away” for decades, recent advancements and growing investment suggest a more optimistic timeline. While widespread commercial fusion power generation is unlikely before 2050 or 2060, some start-ups are aiming for electricity generation by the 2030s. The “ITER” research reactor* is scheduled to achieve first plasma around 2033-2034, and a demonstration reactor (DEMO) is planned for operation around 2050.
*A large-scale international nuclear fusion research project in France, aiming to build the world’s largest tokamak (a type of fusion reactor). The temperatures inside the ITER Tokamak must reach 150 million °C, or ten times the temperature at the core of the Sun. The hot plasma must then be sustained at these extreme temperatures in a controlled way.
It was Seafair weekend here in Seattle.
So the Blue Angels were in town to give their airshow yesterday and today.
Down below on Lake Washington, there were the hydroplane races (high-speed boats that skim across the water’s surface).
These jets are F/A-18 Super Hornets.
From the Blue Angels website: The basic acquisition price of a single F/A-18 Super Hornet is approximately $67.4 million. The cost of additional weapons-related equipment varies according to the configuration, and the use of each aircraft can significantly increase the total price.
The F/A-18 can reach speeds just under Mach 2, almost twice the speed of sound or about 1,400 mph. The maximum rate of climb of the F/A-18 is 30,000 feet per minute.
Cade Metz reports from San Francisco for the New York Times:
An artificial intelligence system built by Google DeepMind, the tech giant’s primary artificial intelligence lab, has achieved “gold medal” status in the annual International Mathematical Olympiad, a premier math competition for high school students.
It was the first time a machine — which solved five of the six problems at the 2025 competition, held in Australia this month — reached that level of success, Google said in a blog post on Monday.
Google said Deep Think had spent the same amount of time with the I.M.O. as human participants did: 4½ hours. But the company declined to say how much money, processing power or electricity had been used to complete the test.
I looked up the problems online, and here they are.
Oof. Should I give it a go, and put in two sessions of 4½ hours each?
I think I’d better not. I might damage my self-esteem. 😆
As part of the ever-expanding scope of my collection of South African stamps, I have started to collect revenue stamps of the South African colonies.
(Before the establishment of the Union of South Africa in 1910, South Africa consisted of four British colonies: the Cape Colony, Natal, Transvaal, and the Orange Free State.)
*A suzerain is a person, state or polity who has supremacy and dominant influence over the foreign policy and economic relations of another subordinate party or polity, but allows internal autonomy to that subordinate.
This yellow revenue stamp with green ink from the Cape Colony is affixed to a checque (using the queen’s English— Queen Victoria) that was issued in 1897 by the Harrismith branch of the National Bank of the Orange Free State.
The Cheque
Written by the treasurer (Charles Truter) of the Dutch Reformed Church on Nov. 9, 1897 to Esquire J. Theron. (Esquire here is the title of a young nobleman).
The cheque is from the Harrismith branch of the National Bank of the Orange Free State, written for an amount of 11 Orange Free State pounds*, 8 shillings, 6 pennies.
*Like the South African pound, it was divided into 20 shillings, and a shilling into 12 pennies.
On the far left of the check is the coat of arms of the Orange Free State.
The cheque was printed by William Brown & Co. of Old Broad Street in London.
Security features at the time included the fine print at the bottom of the check, and so-called fugitive printing, that would use ink that would change, fade, or disappear under specific conditions, if it was tampered with.
The revenue stamp was affixed to the cheque on Nov. 15.
The check was stamped ‘Paid’ on Nov. 19. It seems Esquire Theron had the amount of the check paid into his account at the African Banking Corporation Ltd. in the town of Worcester in the Cape Colony.
A hole was punched in the check to also indicate it has been cashed.
Three amigos ran out to Marymoor Park by Redmond this morning— the site for the Electrify Expo Seattle 2025.
