Boys and girls!

December’s here again already. Over the next few weeks there’ll be the usual Christmassy-New-Year good vibes, then there’ll be the presents, fireworks, champagne, mistletoe, more champagne, and then the clock will strike midnight and we’ll have a +1 to the eternal yearly calendar. Then, for perhaps the first few weeks of January we’ll all still be saying and writing the date as day/Jan/the year 2017; oops, 2018! We all do it! I think ).

Twenty-eighteen. It has a ring to it; yes – a nice, round number. And each numeral that makes up the date is an even number… What? You’re not sure about 1? Come on! 1 is 2 to the power of zero. Kinda :). But wait! There’s more even-ness in this number: each digit of 2018 is a power of two. But what don’t you like about zero? Well, think of an artificial number, raising it to the power of which two gives zero – what, difficult? Now think of an imaginary ‘i’, the square of which gives -1. Come on: such a sexy number as 2018 is just crying out for working a sweat up about :).

Ok, ok; agreed. We won’t spoil arithmetic with all kinds of unnecessary chimeras, to the power of which each decent two turns into an empty zero. But then, as per Chinese tradition, eight means wealth! So get ready – 2018 should be blessed with prosperity; there’s no chance of avoiding it!

Sooo. It’s time to stretch and warm up for what is bound to be an infinitely interesting – and perfectly prosperous – year. So let’s get stuck into some 2018-related arithmetic. And what comes to mind first? Yes: evenness.

2018 = 2*1009

1009 is a prime number. A bit like 2017. Last year I promised that 2017 would be a simple, straightforward year. And look how in the end it turned out! Now we need to get ready for an extra-simple/straightforward year, aka – a minus plus a minus gives a plus.

What else? The sum of all the numerals in 2018 is 11: a most photogenic number from any angle, and one that’s dear to me for technical reasons: the product of all nonzero numerals = 16, which can’t not raise the spirits of any programmer on the planet.

Ok, enough. Warm-up over. Let’s move onto our already traditional New Year arithmetic exercise. Here we go…

Given figures: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1. Using only ‘+’, ‘-‘, ‘*’ and ‘/’, plus ‘(…)’, all in any quantity, and also using exclusively these figures only once and only in that order… – how do you get 2018?

For example:

((10 + 9 – 8) * 7) + (6 + 5) * (4 – 3 + 2) + 1 = 111

Here we get 111. But we need to get 2018!

Marks, get set, go! Who’ll do it first to become the champ?

10 9 8 7 6 5 4 3 2 1 = 2018

Once you solve it, you go to level two: Get 2018 from the same figures minus the 10.

9 8 7 6 5 4 3 2 1 = 2018

Got it? > Level 3…:

8 7 6 5 4 3 2 1 = 2018

I managed these without a calculator – and without peeking at last year’s brainteaser – in around 20 minutes in Shanghai waiting for my flight to Moscow. My attempt at the next one was interrupted of course by the inevitable ‘turn off your devices’ nonsense on the plane, but once the ‘seatbelts fastened’ light went off, I carried on where I’d left off:

7 6 5 4 3 2 1 = 2018

This one is impossible without a factorial. I think we could allow here powers and roots too.

6 5 4 3 2 1 = 2018

Here I needed a multifactorial.

All righty. From ten figures to six: done. We’re half way there. Next up will be the second part of the brainteaser: from five and down. But we’ll save that for next time. For now, I’ve a party to get to!…

Cheers!

Hi folks!

Herewith, more on my time-warping theme, and on assorted tourisms – or their absence.

Sometimes I forget just how much city-hopping on planes I do in a month. It’s only when I look back over the month – usually by going through the photos I’ve taken during it – that I realize the actual numbers of cities visited are in double figures…

So, November 2017 for me went like this:

Like? I didn’t really. That was a tough November. I changed country (admittedly, twice three times – Germany, the UK and Russia) 11 times. I think that might be a record for a month – unless December beats it!…

Next up this month: Wuzhen, China.

Sometimes it seems such a shame there are just 24 hours in a day here on planet earth – normally. But it is possible to have less (why would anyone want that?), or – hurray! – to have more, if you’re careful with your choice of globetrotting-by-plane or certain-national-border-hopping-on-the-ground, that is…

But there are also occasions when you can lose a whole day, as in – a certain day you never see at all, it just passes you by or just never exists for you, and not because of a sleep-athon or coma or some such… I wonder – does that make you a day older? Younger? Hmmm.

So, how can you have a day just never occur for you? Well, here’s an example:

You board a plane, let’s say on August 28 and 14:30 in Santiago de Chile, and 14 hours later, with no night falling during that time, you land in Sydney de Australia. The local time at the destination: 17:30. But the day? August 30! WHAT? Where’d the full 24 hours of August 29 go? It disappeared down a black hole of time, aka the International Date Line. But if the IDL is imaginary… so, that means the day disappeared because of something only imagined and not real? Ok, I’ll stop there before your brain fries more than mine…

To help soothe your frazzled brains, herewith, a few entirely unrelated pics for your viewing pleasure, just when you need them most:

On the other hand, I’ve often had days that never seem to end.

For example, I’ve been woken up at around 2am by my alarm clock (hate that) in Thailand after a partner conference so as to get to the airport in time for my flight departing at 6am – to Tokyo (a timing/route mercifully since closed). Next up – a connection to San Francisco, California. All that in ONE calendar day (kinda), which ends up lasting something like 35-40 hours. Of course, one’s mental state upon arrival at the final destination is a cross between that of a vegetable and a zombie: red eyes, one side of the face lower than the other, perma-frown, very grumpy, etc., etc.: not a pretty sight. But what can you do? Duty calls.

So that’s how regular long-haulers lose or gain hours to their lives up in the air. Meanwhile, down on the ground you get a similar thing, only on a much smaller scale. You can’t go anywhere near as fast as a plane, so the most you can add or take off a day is an hour or two, possibly three at a stretch; more – only if there are two hours’ difference on a border and daylight saving time affects things.

So where can you get spookily-vanishing or magically-appearing hours of a day on the ground?

The first inklings of a theory of volcanic superiority over lava-free mountains first came into existence 10 years ago when I first visited Kamchatka and climbed up my first volcano. It was during that ascent when I started to understand the reasons why I’m so attracted to volcanoes and not to inert mountains. And ever since then ideas of volcanic superiority have been developing into a near-complete theory, which I want to tell you about in this here blogpost.

Quick caveat: straight away I want to apologize to readers who are mountaineers, mountain walkers, or just plain mountain lovers, and also to those whose job it is to organize mountain expeditions. This text is in no way an attack on all things mountains; it’s just a collection of my own observations – possibly including mistaken ones.

I’ll start with a simple question:

How many countries have volcanoes as national symbols? Armenia, Tanzania, Japan… And how many have mountains as national symbols? Hmmm – can’t think of any except for Slovakia. Can you?

I suppose I could have ended this post here: the proof of the pudding volcanic supremacy is in the eating number of national symbols. But no, just to convince any of you doubters (including those who’ve already looked up Kriváň mountain:), I’ll continue. And I’ll begin with the simplest and most obvious preeminence: beauty.

Reason 1: Beauty. In my whole touristic career I’ve been to 24 volcanoes, and I do think you have to visit plenty of volcanoes to be able to boldly state they’re a better species of natural phenomenon than mountains. Well that’s that box ticked for me.

Of course there do exist beautiful mountains, but volcanoes resemble perfect pyramids a lot more often than do mountains. And should a mountain ever have similar characteristics shape-wise, then it’ll inevitably be referred to as ‘as beautiful as a volcano’.

Sometimes, trying to save time sees you spending even more of it…

Every now and then you hear a frustrated business traveler complaining about it taking longer to get to the airport than to fly to their destination. Well, this time that business traveler is me, for I’ve just set myself a record: a recent drive to an airport took twice as long as the flight itself! It was in London, but the airport wasn’t Heathrow or Gatwick or Luton, it was London City Airport – just 18 kilometers from our hotel near Hyde Park: a lot nearer. But we were driving for a whole 90 minutes! Oh my grrrr.

// And before you wonder why we didn’t take the Tube, let me just explain that we had with us fat and heavy suitcases to see us through a whole week of business traveling across four countries. Tried it before; the only conclusion: never again! The Underground is far too cramped for comfort with big suitcases.

Oh my G-force. The Formula 1 season’s over! Where did that go?

What can I say? Well done to Mercedes, is what. Unrestrainable and uncontainable they are. I mean, the Merc racing cars are pretty much the same as the Ferrari ones, but as a team they make less mistakes. The fearless Finn and the blazing Brit together make a fearsome twosome – a more level-headed and self-possessed one than Ferrari’s German-Finn combo, it turned out. In Baku Seb… forgot his age and national character traits, while in Singapore… no – let’s not even mention it. All the same – staying positive – we are at least one point up in the Constructors’ Championship.

So what about Sunday’s race? Well, of course it was on the Yas Marina Circuit, so it was never going to be a ton of fun. Our F1 fanatics always complain about how dull it is: boring turns, a lack of overtaking possibilities, and so on. But, as they say in Russia, to a bad taxi driver a round steering wheel will always be square :). The Benz boys won fair and square – at least to non-insider spectators. There were all sorts of rumors about behind-the-scenes pressure on the new owners of Formula One, but I don’t know the details and so can’t comment on them.

But now about the race.

The best bits of any race are of course the start, the tactical controversies throughout the race, the overtaking, and the pit stops. I think the pit stops are best of all: so long as you don’t blink! Three seconds and they’re done!

Guten tag folks!

After a practically horizontal weekend (intense recuperation after the previous weeks’ long slog) and a day-and-a-half in the office in Moscow, before you could say das ist fantastisch, I was heading back to Deutschland. On the agenda: two days, two cities (Frankfurt and Berlin), four speeches, dozens of interviews, an event for partners. Then home again for another horizontal weekend to sufficiently recharge the batteries for yet another busy schedule the following week.

So. Frankfurt. What can I say? Well first here’s what I can show:

In my Top-100 Must-See Places in the World, there’s a special section on China. So why does this single country get a section all of its own (as Russia does) unlike most other countries? Simple: it’s packed full of touristic wonders; it’s only they’re hardly known about outside the country. China is in many ways a self-sufficient country, and that includes in terms of its domestic tourism. China has no real need for foreign tourists: it has plenty to be getting on with from inside the country ).

Anyway, I regularly (but quietly) add new places to the China sub-list of my Top-100 list, based on my travels around the country. So here’s my latest update adding new data and recommendations to the list…

1. The Longyou Caves.

The Longyou Caves – meaning Dragon Caves – were discovered in 1992 when some locals were pumping water from a pond. You can image their surprise when they came across this lot! It turned out to be ancient man-made caverns – ‘secret’ (unrecorded) ones at that; MASSIVE ones at that (they scooped out a whopping MILLION cubic meters of bedrock to make them!). I mean, how do you (rather, you and, say, an army of laborers) keep that undertaking (which clearly lasted decades) quiet so no one at all knows about it/writes about it? All a mystery. And, accordingly – very must-see!

Here’s some detail on the caves; here too (photos are from here).

Just a 30-minute drive from the German city of Mannheim is the picture-postcard town of Heidelberg. If ever you’re in the vicinity and have some time to spare – a day or even just half of one should be spent here.

Be careful what you wish for!…

…I’d been wishing for an aerial view – from an airplane – of Santorini for years. Well now it’s come to pass.

I had in fact flown over the Greek island before, only at night and/or on a cloudy day, so I never saw anything. This time, the conditions were perfect: a bright, clear day. The conditions were so perfect that even the pilots were taking pics!

Santorini!
