Like an Event, an Observable is a sequence of values that a data producer pushes to the consumer. However unlike an Event, an Observable can signal to a listener that it has completed, and will send no more data.

Querying Arrays only gives us a snapshot. By contrast, querying Observables allows us to create data sets that react and update as the system changes over time. This enables a very powerful type of programming known as reactive programming.

Disposing of a Subscription object unsubscribes from the event and prevents memory leaks. Disposing of a subscription is the asynchronous equivalent of stopping half-way through a counting for loop.

If we convert Events to Observable Objects, we can use powerful functions to transform them.

	This announcement is preparatory to the forthcoming tender for the exploration and extraction of Lithuanian amber resources.

	It was proposed that the tax should be 20% that of the amber market value. However, amber market prices in Lithuania have not been reviewed since 1992. In comparison, the same tax ranges between 15-25% in the rest of the European Union. This is equal to an increase from 20.2 EUR/kg to 280 EUR/kg for the amber fraction of up to 40 millimeters, and up to 900 EUR/kg for amber fraction greater than 40 millimeters.

	After the government meeting Prime Minister Algirdas Butkevičius told reporters that tax increase should not deter potential amber exploration and production bidders:

	“The international demand and price of amber is considerably higher. It is not a cheap commodity.” – said the Lithuanian prime minister.

	According to the Ministry of Environment, tax increase will generate an income of 41 million EUR:

	About four months ago I have bought an air humidifier (Dyson Humidifier). I have set it to maximum and left it next to my bed – I thought it will help my skin. It did. However, few weeks later a ringing started in my head (high-pitch) and then a more noticeable ringing in my right ear (low tone). ENT doctor have not found ear damage or change in my hearing. The cause is unknown.
	Air humidifier was about the only change in my life around that time. I am not jumping to the conclusions. Quick Google search for tinnitus and air humidifier came back with nothing. Going to throw this out in case more people observe a similar happening and start to Google.
