World of Arts: Botanical Arts

Botanical paintings helps to recognize species of plant. Photo by: Işık Güner 

Perhaps one of the most popular form of arts. Not as popular as portrait paintings, but plays important roles in human advancement in scientific studies and medicine. Same at any other form of arts, botanical paintings evolved from thousand years ago. Anyway, they play different roles with the advancement of technologies. Today, we have better ways to record botanical specimen, and at the same time the botanical arts helps to deliver what the modern technology cannot do.

Botanical arts or paintings were used in order to recognize types of plants that can be used for medical purposes, or plants with commercial values such as herbs and spices. When the botanical knowledge getting larger, the botanical paintings/illustration helps to segregate plants into their family and species that also helped human to develop new crops that produce more yields or immune to some diseases.

Today, botanical artist can choose to fulfil all of these purposes. They have a broad range of purposes in delivering their arts. They can do botanical illustrator with high accuracy details, in order to help botanist to recognize plant species for recording purposes. They also can do botanical art to show their subject’s aesthetic value. This type of art is the best to medium as an introduction to those who never get exposed to botanical illustration or botanical art before. The last approach that artist can do is through flower painting, without accuracy. This creative approach just as any other painting by representing plants just by artist creativity and imagination.

No matter which types of approaches that you are working on, botanical art is one of the best ways to preserve the plant specimen. Today, botanical artists can produce higher accuracy illustration and arts with the use of higher quality materials. The artist’s hard work, then share for many other viewers, through publication and exhibition. This beautiful result not only works educational medium, but also as piece of art at the same time.

There are many botanical artists out there that sharing their knowledge through free and paid courses. You don’t have to be as good as the professional botanical artist to help recording the backyard’s specimens - just follow few important keys to make sure you are doing it right.

We will see some of the botanical artists that we can learn from their YouTube channel. Other than that, we also can learn from books or DVD’s we can buy through online. Visit the exhibition is another good practice to learn from other artist works. We will improve faster when learning from those who already mastered the fields.

Hopefully botanical arts will grows among all of us in order to collect botanical data from all over the world. Because plants change so fast (produce new species), without proper record, we might lose many important plants that important to our survival. Enjoy the nature, embrace their beauty.

Natural History Museum, London

The Natural History Museum as you get to its front entrance.

Another worth visit in London is to Natural History Museum, located in South Kensington. Not only housed a huge collection of specimens, this museum also collaborated in many scientific research, especially related to nature and conservation. Located on Exhibition Road, next to two other popular museums (Science Museum and the Victoria and Albert Museum) in London, Natural History Museum lure its own unique visitors from all around the world.

Natural History Museum previously was known as British Museum (Natural History) until 1992. Even though the legal separation from the British Museum was happening earlier in 1963. That’s part of the story of the Natural History Museum, even though, as we know the beautiful Alfred Waterhouse building was opened in 1881 - and the museum keeps on expanding its collections together with its roles in educating the public and research.

The gigantic blue whale skeleton at the Hintze Hall.

This moa (Dinornis novaezealandiae) was identified by Richard Owen only by its single fragment of bone (before it was completed).

There are many reasons why people are attracted to this museum, especially if they watched the documentaries by the BBC or National Geographic. More than that, educator and students also need to see by themselves all the specimens on display in order to understand more about the nature (especially when it comes to dinosaurs and specimens outside of their geographical areas).

Here at this museum, everyone is dedicated to give their best in their field start from its first Superintendent in 1856 the palaeontologist Richard Owen. Richard Owen was known to be very detailed in identifying all the specimens to make sure it is original. From there the Natural History Museum keeps on expanding its function and change the way we look at the museum.

The mineral collections from the Earth Hall.

The best experience starts soon after you see this magnificent museum’s building. Rather than just huge, it is carefully designed with beautiful façade and animal sculptures will make you astonished. If you can, make sure you visit this museum during the weekdays, as during the weekend or public holidays it will be long queues of people from all around the world. But that’s not all, there are many other surprises of the building’s architectures that will amaze you before you even see any of its exhibits.

Since its establishment in 1881 until today, this museum specimen now comprising of some 80 million items with five main collections: botany, entomology, mineralogy, palaeontology and zoology. Only some of these specimens will be shown in its exhibitions, while most of the specimen being kept for conservation and research purposes. If you are lucky, you might be able to see some of them if there’s any special exhibitions during your visit.

Same as the previous visit to Kew Gardens, it is important for you to make sure what is the main things you want to see in this museum? One day visit won’t be enough for you to explore the whole collections displayed on their exhibition halls; unless you just wandering around without any attention to the collections.

You can check their floor plan in advance and at the same time, check the interior of the museum through Google Maps to get an idea which is where - so it will help you to decide which areas is more important. You also need to check their website for more details about the current exhibitions (as sometimes there will be additional information regarding closure of exhibitions too).

The dinosaur is one of the important specimens here.

I need to visit this museum twice when I visited London recently (first visit was two hours and the second visit was around four hours: still I missed few areas). As I need to speed up my observations, I took as many photos as I can for future reference (and I put it in the fanpage album so we all can see it). The light condition in the museum also is too dim, so taking photos is a little bit tricky!

There are many things happening around here at the Natural History Museum. Not all of it you can see during your visit, the details of these activities are posted on their website. You might want to see about the usage of new technologies in order to unravel many things that we still don’t know about the nature. Then, with the latest technologies too, the information will be shared with the public - you need to check the 3D skeleton ofthe blue whale.

There are many other interesting information available on their website, where you also can become a member to get membership benefits. If you are interested in nature and sciences, Natural History Museum is one of the place you should visit. I hope I have shared some important information here and the rest is up to you. If you have any question or information to share, don’t hesitate to share it at the comments section below or email it to me at wikipelajar(add)gmail(dot)com.

Terrarium Suitable For Ornamental And Education

Terrarium best as decoration and good as educational material.
Terrarium usually made from small container (clear/glass materials) that will allow light get through it. The container can be open or closed and small opening to allow care for the plants grows inside it. Even though terrarium is very beautiful as ornamental it is also very important for education to understand more about plants growing process and behavior.

Construction of the first terrarium is produced inadvertently by botanist Nathaniel Bagshaw Ward in 1842. He made observations of insects and the insects left the flask unattended. As a result, spores contained in the flask grow and produce terrarium. This later became a favorite at the time (Victorian Era) among the British people. But at first it was not known as terrarium but as 'Wardian Case'.

This finding was used by Ward to send the plants from England to Australia by building a bigger 'Wardian Case'. Even after traveling for months at sea, the plants were found to be in good conditions. The same method was also used to bring plants from Australia (Sydney) to England (London). This method proves that plants can be stored in a sealed container without ventilation and are capable of living.

Terrarium more popular for decoration.
Closed terrarium provides moist environment for the plants in it.
Among the plants that are suitable for terrarium.

Even so, before you build your terrarium, there are few things that you need to pay attention. This because you need to think about a few important factors to allow the plant stored in your terrarium can produce enough cycle for itself to continue its life. In fact, several other factors should also be considered before producing the terrarium; container size, container type, species of plants, location of the terrarium, the amount of moisture, the plant material (soil, sand, stone, fiber, etc.) and the budget of the terrarium - if you planning is right, your terrarium may endure for a very long time.

Closed Terrarium

Closed terrarium suitable for indoor tropical plants like orchids, mosses, ferns and ‘air plants’ that need high moisture as in tropical forests. However for its care, it may have to be opened once a week to reduce excess moisture in the walls of the container, this also able to prevent the formation of fungus that can affect plants inside your terrarium.

Terrarium should be watered when the soil moisture is decreasing (without the formation of water vapor on terrarium’s wall). The use of plant materials (medium) also carefully sorted to reduce infections in plants. Appropriate plant material used is 'peat moss', 'vermiculite' and also 'perlite'. These materials should also be in "sterile" for killing micro-organisms that can cause infection.

Terrarium provides a very good environment for these tropical plants.

Terrarium for tropical and aquatic plants.
Open Terrarium

Open terrarium is more suitable for water-storage plants (succulents) that are not suitable for damp and closed conditions like cacti and other dried plants. Open terrarium allows excess water vapor to be removed from the terrarium. Another thing open terrarium also ideal for plants that require a lot of sunlight, where it avoids excessive heat from sunlight trapped in the container.

Open terrarium easily maintained but at risk of infection.
Terrarium with various sizes of plants in it.

Terrarium not only beautiful as a decoration/ornament, but it also allows the growth of plants to be observed more closely. Cyclical process of moisture, air and water vapor in a closed terrarium indirectly describes the process air cycle in the earth's atmosphere and the importance of plants in that process. So if you are unable to make your own terrarium, maybe you can just buy it to get all of its benefits.
