In October 1982 I published an article entitled "Laser technology - breakthrough successful" as the specialist editor of "Idea - Das Magazin für Ingenieure". Since holography was one of my areas of specialization during my studies at the Ruhr University in Bochum, this interesting and future-oriented technology should of course not be missing. In order to cover the wide range of their areas of application, e.g. to round off the nondestructive testing of materials, etc., the artistic aspects of holography should also be examined. While researching, I found Mr.

The most famous Bhutanese monastery in Bhutan, the Taktsang Monastery (short for Paro Taktsang Palphug Monastery) is located in the Paro valley at an altitude of 3120 meters. It is also called the Tiger's Nest Monastery because it "hangs" like a nest on a steep rock about 700 meters above the floor of the Paro Valley in Bhutan. On the other hand, there are several legends that explain this name, e.g.

Traveling to Bhutan takes a lot of preparation. For example, during our planning phase we had to organize driver, guide and compulsory exchange into local currency.

Only groups of 4 people or more were allowed to enter but it was particularly lucky that we were given permission to travel to Bhutan in pairs.

Kauai, the garden island, lures with impressive trails to waterfalls and the lush cliffs in the north of Kaua'i stand in stark contrast to the drier west side. There are long sandy beaches on the coast and the heavy surf can sometimes be threatening. We had strong wind and the palm leaves flew past the window of our hotel, so that weather-related hikes were out of the question. But after the storm subsided, we went out into the impressive landscape.

There was a special attraction on the coastal road. At night, the current lava flow had made it impassable. The nearby volcanic spots showed corresponding remains of past lava flows. In addition to tree skeletons, lava columns could be seen, which are created by coating them with flowing lava from trees. Once the organic tree remains have disappeared, the lava columns remain as memorials.

With a little luck we were able to get accommodation directly on the crater rim at the Kilauea volcano. The former Sheraton Hotel and today's Volcano Home offered a fantastic starting point for exploring the Hawaii Volcanoes National Park. This is an approximately 1348 square kilometer biosphere reserve in the southeast of Hawaii, which has been a UNESCO World Heritage Site since 1987. The area includes extensive lava fields and the active Kīlauea volcano. (Wikipedia)

We explored the volcanic world of Big Island from various locations and initially moved to Hilo Quartier, as it is easy to get to the two volcanoes Mauna Loa and Mauna Kea. In our hotel we found a tsunami warning after an excursion and we quickly packed up the photo things to go to the coast - luckily the wave was only 1.80 m high, otherwise this recklessness might have been dear to us. The drive to Mauna Kea was difficult. But we wanted to see the observatory. The largest telescopes in the

Hawaii or Big Island is the largest island in the US state of Hawaii. When the "Pacific Plate" moved over a hot spot in this region, the volcanoes that formed the current morphology of the island emerged. The five largest volcanoes are called: Kohala, Hualalai, Mauna Kea, Mauna Loa and Kilauea. At the top of Mauna Kea, the Mauna Kea Observatory is one of the most important astronomical observatories.

When you talk about Hawaii, you think of hula, volcanoes and surfing and places like Waikīkī, a district of Honolulu, the capital of the state of Hawaii. Waikiki with its famous hotel beach and the Kalakaua promenade is the tourist center of Oahu. Honolulu means "protected bay" and has 337,000 inhabitants. (Wikipedia)

Honolulu was also our first port of call on our trip, fromwhere we started to visit four of the impressive Hawaii islands.
